In this paper, we consider an amplify-and-forward (AF) transmission based multi-hop cooperative relay network operating over generalized-K fading channels. The generalized-K fading channel is general enough to incorporate most of the composite multi-path fading and shadowing channels which are widely encountered in real-world environments. In this paper, novel closed-form expressions for the average...
In this paper, the performance of cooperative networks introduced in the literature is analyzed for asynchronous direct sequence code-division-multiple-access (DS-CDMA) systems in frequency-selective slow fading environment. We show that the full benefits of cooperative diversity cannot be achieved if no multiuser interference suppression is employed at the cooperative end. We consider two scenarios;...
In this letter, we examine the symbol-error-rate (SER) performance of decode-and-forward (DF) cooperative communications. Our focus is on the scenario in which multiple dual-hop relays are employed and the channel environment is described by Nakagami-m fading. Cooperative diversity is observed from the derived error-rate expressions, and some insight into how channel conditions in the relay nodes...
