The performances of the decode-and-forward (DF) multihop free-space optical communication system with exponentiated Weibull distribution considering the fading induced by pointing error have been studied. With Meijer's G-function, the probability density function (PDF) of the aggregated channel model and the closed-form expression for the average bit error rate (ABER) of binary pulse position modulation...
In recent years, the MIMO-based underwater acoustic (UWA) wireless sensor networks have attracted significant research attention because of its wide and critical applications in marine research, oceanography, marine commercial operations, offshore oil industry, and defense systems. The cooperativecommunications- based wireless relay networks have been widely cited as a very efficient technique to...
Multi-path fading, one of the key factors that deteriorate quality of service (QOS) in Underwater Acoustic Networks (UANs), is investigated under different underwater scenarios in this paper. To improve the Bit Error Rate (BER) performance, the techniques of cooperative diversities are applied. Considering realistic physical model and cooperative diversity techniques, two asynchronous forwarding schemes,...
