Conference Paper: C6. Probability of error of TDMA relay protocols over Weibull and Weibulllognormal channels
[Show abstract] [Hide abstract]
ABSTRACT: This paper focuses on the analysis of the probability of error for several timedivision multipleaccess (TDMA) cooperative wireless twostage relay protocols using amplifyandforward (AF) over independent nonidentically distributed Weibull and Weibulllognormal fading channels with maximal ratio combining (MRC) reception. A closedform expression for the momentgenerating function (MGF) of a lower bound on the total endtoend signaltonoiseratio (SNR) is derived in terms of the tabulated Meijer's Gfunction. The MGF is then used to derive the probability of error for relaying with orthogonal channels. Simulation results are presented to show that the probability of error expression becomes tight at high SNR values thus verifying the lower bound approximation results.Radio Science Conference (NRSC), 2012 29th National; 04/2012  [Show abstract] [Hide abstract]
ABSTRACT: We investigate the ergodic capacity of amplifyandforward (AF) dualhop relaying systems in composite Nakagami$m$/inverseGaussian fading channels. This type of fading, which is known in the literature as ${\cal G}$ fading, has recently attracted increasing research interest due to its ability to better approximate the Nakagami $m$/lognormal model, compared with the Nakagami $m$/gamma model. We study both fixed and variablegain relaying systems and present analytical upper and lower bounds for the ergodic capacity of dualhop relaying systems with not necessarily identical hops; these bounds provide an efficient means to evaluate the ergodic capacity of AF dualhop relaying systems over ${\cal G}$ fading channels. We also establish sufficient conditions for the existence of the bounds, depending on the values of the fading parameters. In both cases, our simulation results demonstrate that the proposed upper and lower bounds remain relatively tight for different fading conditions.IEEE Transactions on Vehicular Technology  IEEE TRANS VEH TECHNOL. 01/2012; 61(4):17301740.

ABSTRACT: This paper presents the analysis of outage probability for a cooperative diversity wireless network using amplifyandforward relays over independent nonidentical distributed Weibull and Weibulllognormal fading channels for single as well as multiple relays. To reach that end, a closedfrom expression for the momentgenerating function of the total signaltonoiseratio (SNR) at the destination is derived in terms of the tabulated Meijer’s Gfunction. Since it is hard to determine the exact probability distribution function of the SNR, a tight lower bound approximation is proposed. Simulation results are presented that show that the outage probability lower bound tends to be tight at high SNR values thus verifying the analytical results. The results also show the potential gain of relaying on the outage probability.Wireless Personal Communications 01/2012; · 0.43 Impact Factor
