I am curious about what happened to the atomizer software by Buckheit J. (http://statweb.stanford.edu/~wavelab/personnel/) and if it is available somewhere.
Sadly I found only 2 dodgy sites that require a login to download the MATLAB code. Does someone have any information on where to get it from?
Alternatively, if there are other toolkits that have implemented this code please let me know, it does not have to be MATLAB, any language is fine for me :).
Thank you.

Hi everyone,
I am trying to simulate an M-QAM MIMO system, and I want to decode the received signal using QR decomposition and sphere decoding.
However, I am struggling to understand how to implement the simple tree sphere decoding algorithm.
Here's my understanding so far:
Given a receive signal as follows:
1. Y = HX + N;
where X is a K x 1 vector consisting of K MQAM data symbols, H is a K x K fading matrix, N is a
K x 1 AWGN vector, and Y is the K x 1 received vector.
We perform QR detection as follows:
2. H = QR;
where Q is a K x K Unitary matrix, and R is a upper-triangular matrix with entry R(i, j),
with i and j being the row and column indices respectively.
Then we equalise the receive signal in 1. as:
3. Z = (Q^H)*Y = RX + (Q^H)*N , where Q^H is the Hermitian transpose of Q.
I now want to perform Sphere decoding based on 3. This is where I am struggling.
My best attempt at coding this algorithm in Matlab is shown below (Assuming K = 8, and assuming an arbitrary radius d):
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% ## Inputs:
% # R, upper triangular matrix
% # Z,vector receive signal
% # d, radius of sphere
%
% ## Output
% # X_hat, vector of estimated symbols
n = 8; % n => K
d_vector = zeros(1, n);
d_vector(n) = d;
Upp_bound = zeros(1, n);
Low_bound = zeros(1, n);
minR = d_vector(n);
intersum = zeros(1, n);
intersum(n) = Z(n);
Upp_bound(n) = (d_vector(n) + Z(n))/R(n, n);
Low_bound(n) = (-d_vector(n) + Z(n))/R(n, n);
X_hat = zeros(1, n);
% ## begin algorithm
if Low_bound(n) > Upp_bound(n)
return null;
else
X_hat(n) = Low_bound(n);
end
k = n;
while X_hat(n) <= Upp_bound(n)
if X_hat(k) > Upp_bound(k)
k = k + 1;
X_hat(k) = X_hat(k) + 1;
else
if k > 1
k = k - 1;
d_vector(k) = sqrt(d_vector(k)^2 - (intersum(k + 1) - R(k + 1, k + 1)*X_hat(k + 1))^2);
intersum(k) = Z(k) - R(k, (k + 1):n)*X_hat((k + 1):n);
Upp_bound(k) = (d_vector(k) + intersum(k))/R(k, k);
Low_bound(k) = (-d_vector(k) + intersum(k))/R(k, k);
if Low_bound(k) > Upp_bound(k)
k = k + 1;
X_hat(k) = X_hat(k + 1);
else
X_hat(k) = Low_bound(k);
end
else
while X_hat(k) <= Upp_bound(k)
if minR > norm(Z - R*X_hat, 'fro')^2
X_est_vector = X_hat; %found X_hat
minR = norm(Z - R*X_hat, 'fro')^2;
end
X_hat(k) = X_hat(k) + 1;
end
k = k + 1;
X_hat(k) = X_hat(k) + 1;
end
end
end

Please could you tell me where I might be going wrong.
Thank you.
Hi everyone,
I am trying to derive the error performance of a wireless communications system, and I run into a series of Independent and Identically Distributed (i.i.d.) random variables (RVs) as follows:
Z = X_1 + X_2 + ... + X_N,
where N denotes the number of RVs being summed together. The distribution of each X_1, .., X_N may be Rayleigh, Rice, etc.
Now, I know that the Central Limit Theorem (CLT) can be applied assuming high N, such that the mean of Z becomes:
E[Z] = N*E[X_N],
and the variance of Z becomes:
Var[Z] = N*Var[X_N].
However, in my case, N is not high enough to use CLT. In fact, I am working with N values in the set N = {2, 3, 4, 5, 6, 7, 8, 9, 10}.
So my question is, if I am given the CDF (denoted by F_N(t)) and PDF (denoted by f_N(t)) of each X_1, ..., X_N, how do I evaluate the mean and variance of Z? Do you use some sort of convolution property, or something else?
Any help would be appreciated.
Thank you.
What is difference between spin-transfer torque nano oscillators and spin-hall nano oscillators?
In optical wireless communication, there are two main system architectures:
• Intensity modulation and direct detection (IM/DD)
• Coherent modulation/detection
In IM/DD systems, the optical front-end can only detect the optical intensity while coherent receivers can detect both amplitude and phase.
Discuss how we can benefit from Integrated reflective surfaces in IM/DD and coherent optical wireless systems. For each system type, explain your underlying assumptions and any other essential information to support your arguments.
Hi everyone!
I want to have expertise opinion abut these.
Will it be cost effective or not?
What about the signal strength (SNR) and system complexity?
Hi everyone,
I wanted to know how to perform Rician fading in matlab.
I have done Rayleigh fading, which is simply:
h = sqrt(1/2)*(randn(1, 1) + 1i*randn(1, 1));
From what I understand so far about Rician fading, it is computed in terms of a Rician factor K, and a scaling parameter Omega (I will assume Omega = 1). It is also computed in terms of Line-of-Sight components and Non-Line-of-Sight components.
So what i did was:
hLOS = sqrt(1/2)*(randn(1, 1) + 1i*randn(1, 1));
hNLOS = sqrt(1/2)*(randn(1, 1) + 1i*randn(1, 1));
h = sqrt(K/(K + 1))*hLOS + sqrt(1/(K + 1))*hNLOS;
I want to confirm if this is correct or not. If it is not, please could someone offer some guidance on how to correct this.
Thank you.
How to filter input signal through lognormal shadowing model or kappa mu shadowing model by using a code which generates PDF in Matlab?
i have transfer functions from two different papers. are they same.
in H=exp(-alpha(f)*l)

For generating antenna pattern multiplexing when we apply dc biased sinusoidal voltage to the variable reactance of the Electronically Steerable Parasitic Array Radiator (ESPAR) antenna, the received signal appear as harmonic due to non linear properties resulting loosing signal components? which method can minimize the issue for making the antenna pattern more efficient?
In many books and papers, they used to use the complex form of the channel effect response. However, in reality, the signal is real values and also the channel.
Is it correct to use the following approximation? (in MATLAB)
% Rayleigh channel fading
eta = 4; %Path loss exponent
d = 200; %Distance from BS to the user
h_var = sqrt(d^-eta); % channel effect variance, mean is zero
h = h_var*randn(1,length(tx))/sqrt(2);
In a signal is to be transmismitted, first pilot symbols are added and then through Mach-zehnder modulator it has to be transmitted for optical communication purposes. So, for pilot symbols, they have to be go through Mach-Zehnder modulator. The output of Mach-Zehnder modulator is E_out=cos(phi); Where phi= ((U+U_dc)/U_pi)*pi. and here, U_dc, U_pi and pi are constant. And U is the information after inserting pilots. This signal E_out is sent through the channel h.
Now, my question is that how should I estimate the channel because the pilot are gone through Mach-Zehnder modulator before the channel. and How should I extract the pilots and estimate the channel? Thank you.
"Waveguide for port number 1 is too short. The waveguide must be homogeneous for at least three mesh planes along propagation direction" is shown when I run the designed micro-strip antenna by CST software.
Hi everyone,
I am trying to derive the variance of a Random Variable as part of my research.
I wanted to check if I have simplified the expression in the word document attached correctly. In other words, if I take the variance of a sum or difference of linear combinations (series) of random variables, is that equal to the sums of the variances of the random variables, where the different series differ by a constant "alpha" (see the document). Note that the random variable in each series is the same random variable.
I tried deducing this by using a few properties of variance:
1. Var(aX) = a^2 Var(X)
2. Var([series from 1 to n of] X) = n Var(X)
3. Var(aX + bY) = a^2Var(X) + b^2Var(Y), where X and Y are independent RVs.
However, I am not sure if this correct. Please could you check if my understanding of this is correct.
Thank you.
Hi everyone,
I am having a problem deriving the variance of a variable which is expressed in terms of a series expression where the sum term is a random variable.
I have attached a word document which illustrates the types of expressions which need to be evaluated in my derivation of the random variable in question. I hope this is clear enough to explain my problem.
I want to know how to evaluate these types of expressions, where the random variable is part of the series term.
Thank You

For polarization diversity in wireless communication, often dual orthogonal polarization antenna is considered. I want to study the effect of non-orthogonal polarization antennas on wireless communication channels.
how to analyze the non-orthogonal polarization antenna effect to make a proper study of polarization diversity in MIMO wireless communication.
kindly suggest any relevant theory or research papers.
Thank you.
We know that in the Han-Kobayashi region, the to be transmitted data is divided into two parts, private and common. So, what type of information does these parts contain ?
In the textbook of Tse "Fundamental of wireless communications", the LOS MIMO channel model is characterized by $H = \alpha \times a(\theta) *a(\gamma)^H $ where a(\cdot)$ is the steering vector. The model uses conjugate transpose while there are other papers use transpose. This has puzzled me a lot. I understand if the transmitt antennas and receive antennas are different, both of them seem to be right. But how about the full-duplex antennas, which one should be right?
I'm looking for an advises regarding Machine Learning methods applied in Wireless books to solve some optimization problems.
According to my knowledge, the channel estimation is to analyze the channel realization based on the pilot signal, and the channel prediction is to obtain it based on past channel realizations.
Therefore, the channel prediction can be utilized when the pilot signal is contaminated. In other words, the channel prediction is only deserved in the situation when the pilot signals are crashed so that the channel estimation doesn’t work.
Did I understand right? Thank you for your valuable responses in advance.
In the context of wireless communication, I have heard people asking will the AI/ML model be trained online/offline? I would like to know what is the difference between these two terms and how they can impact the system performance?

Most of the authors presented their work on Mach-Zehnder modulator in fiber optic communication. When I saw Mach-Zehnder Modulator on internet for buying it is showing it with fiber optic cable both sides of Mach-Zehnder Modulator(input and oupt side). My question is that can we use Mach-zehnder modulator for intensity modulation in wireless optical communication? Please help.
What are the areas in fading channels like TWDP,Rayleigh fading Channel,Nakagami fading Channels?? ....Is pursuing research in this area are limited?Is there is a chance of publishing many papers in this area?
I am keen to do research in wireless communication. I would like to know research idea in this field.
Both deep learning (DL) and quantum computing (QC) are emerging technologies in the realm of research. Please share your valuable opinion on the following concerns.
- How DL can be merged with QC?
- What are the current challenges in the DL-based QC?
- What are the tentative application areas for DL-based QC?
Thanks for your time.
For Intensity modulation, I am using external modulation. I want to simulate mach-zehnder modulator based intensity modulation. Please suggest simulation in MATLAB
I have an antenna module which is a planar phased array for 5G NR FR2 base station (i.e., BS type 2-O). I need to perform over-the-air (OTA) radiated conformance testing to verify the performance of antenna module to obey specification of 3GPP. Hence, I study the attached file 3GPP TS 38.141-2 V16.10.0.
For transmitter test (chapter 6), the module is connected with a signal generator (SG), which make NR signals generated by SG are emitted through antenna module. And then, a feed antenna is regarded as receiving end and connected with a signal analyzer (SA) and spectrum for analysing received signal. On the other hand, for receiver test (chapter 7), exchange the placements by module and probe antenna to perform conformance testing. The complete transmission and received process run in a CATR or anechoic chamber.
- How to set parameters (ex. total output power, modulation, operation band, bandwidth, frame structure, single or multi-carrier, subcarrier spacing, TDD or FDD, and so on) of measuring equipment (SG and SA) for radiated conformance testing according to TS 38.141-2? Would you mind take an simple demonstration for test items in section 6.2 and 7.3?
In my opinion, the section 4.7.2, 4.9.2 and Annex A is strongly relate to the setup. (I am confused about difference between intention of test configurations and test model respectively in section 4.7.2 and 4.9.2. I googled other materials (others attached file) about this issue, there is only description about Test Model NR-FR2-TM in test procedure rather than Test Configurations NRTC )
I have some base of communication system but I am short of practical experience of RF measurement, so this problem maybe is not an easy question to answer. If you cannot answer by a few words, please provide clues or direction of search.
Many thanks for your answer.
If so, we're hiring! - come and join our team to help develop the next generation of intelligent, wearable drug delivery devices. Research opportunities now available in microsensor integration, transdermal delivery and microfludics, and system electronics/communications. Further details available from Dr Conor O'Mahony - feel free to discuss with us!
In your opinion, what are the interesting and worthy topics for research in wireless communication systems?
Could any one please help me in suggesting some resources where I could find a comparison curve between signal strength after Multi Path propagation effect with respect to obstacle positions between transmitter and receiver.
After conduction some experiment I found that the effect was greater near Rx or Near Tx but lesser when the obstacle is in same distance from Rx and Tx. Why such phenomena happens?
Hello
I am going through some digital communication literature, where some research papers have used the following formula to calculate the sum rate
Sum_rate=Summation (log2(1+SINR(i)) eq.1
My confusion is as follows:
1. Why is bandwidth(B) not included i.e. B.log2(1+SINR)
2. What will be the units (e.g. bps/Kbps/Mbps etc) if eq.1 is used.
Thanks
Hello, i am searching for some new innovation points in 6G about networking slice recently.
I want to know what updates will be made to network slicing in 6G, which cannot do well in 5G.
(Maybe about architectures, methodologies, algorithms, and combination with other 6G new technologies.)
Can you recommend me some good ideas, innovation points or papers( and white papers), thank you.
Recently, I focus on UAV-enabled air-to-air wireless communications, in which the UAVs are flying at an altitude of 60~150 m. In this case, which channel model is more applicable? Intuitively, I think the LoS channel is suitable since there should be no obstacles at this high altitude. Is my idea correct? Could you provide me with some references, thank you very much for your help!
Please guide me about the difference between SINR threshold and Minimum discernable signal.
From my search I have come across the following.
1) A signal can be decoded if the SINR of the received signal is higher than the SINR threshold. Does it mean that we should not be concerned about the minimum required power, and that if the received signal satisfies the SINR threshold, it will be successfully decoded?
2) I also have come across the idea of minimum discernable level. For instance -70 db is considered acceptable for some types of communication.
Which of the two I should follow. As in the first case, I get very low transmit powers and still satisfy the SINR threshold, while the transmit powers in the 2nd case are way too high compared to the first case.
