A reconfigurable antenna has become a vital element in modern communication systems to meet the requirements of 5G networks such as high rate and large capacity, also to do multi-functions in one device. The target of this paper is to design a frequency reconfigurable antenna with microstrip technology to operate over 5G bands. The researchers prop...

Currently wireless communication technology is improving the new generation of data communication, since it has to facilitate the users to communicate and share information or data between them through different wirelessly linked equipment. These scheme of techniques develop and investigate the existing technologies to be easier for the subscribers...

In this research paper, a simulation model is proposed which can be used to evaluate the performance of LEACH protocol in realistic noise-prone WSN environment. In this model, the noise-level is represented by the probability of reception (pr) of packets. When pr is one the network environment is considered noise-free and all packets sent are recei...

Millimeter-wave (mm-Wave) frequencies between 30 and 300 GHz are a new frontier for cellular communication and this band is considered as the potential candidate for high speed communication services in 4 and 5G networks due to its huge bandwidth.This paper discuss the potential applications of mm-Wave communications in the 4 and 5G networks, inclu...

In this paper, the digital equivalent of wiener filter is used for the filtering of image contours represented in X, Y Cartesian coordinates, using different fast transforms. The Wiener filter is a linear estimator and minimizes the mean-squared error between the original and filtered signal. Each coordinate is assumed to be disturbed by a white no...

In digital communication technique the most important issue is to receive data at receiver side similar to the data send from the transmitter side with a high speed using fewer channel bandwidth. This means that it is very important to test the systems in terms of probability of error P(e) to observe the system's performance. Each modulation techni...

Broadband power line (BPL) was used for power transmission. In addition to that, it also gives another important benefit; that is data transmission via it also, the main advantage here is being able to use the existing power network infrastructure, means reducing the cost by 60%. However power line system were not designed for high speed data trans...

Now days he digital systems are very popular and widely used in various engineering areas,especially in monitoring systems, these systems are simple to analysis and design; due to its use logic circuits in their system.This paper treaty of investigation simulation anddesign Alarm Security Monitoring system by using two scientific computer packages...

The highly intensive race among GSM operators for their market share have created a rich environment for an advent of many services beyond core services, meaning just making calls and sending SMS which will refer to it as value added service or VAS. A typical example of VAS: when a mobile user is willing to know weather forecast so he or she get in...

In this paper a simple single-stage single-switch input-current shaping (S4ICS) circuit was designed, simulated and tested for AC/DC converter which generates input current harmonics due to its non-linear characteristics. A sinusoidal input current with nearly unity distortion factor was achieved through current harmonics mitigation by using PWM bo...

This paper deals with the closed loop system called Adaptive Time Delay Estimation (ATDE) for estimating time delay between two signals is presented . The simulation of this algorithm accomplished by using MathCAD package are carried out . The technique that we will present this work is based on the error between two samples of the incoming signal...
