Abstract

We investigate the symbol error rate (SER) and outage probability of the cooperative transmission with the decode-and-forward relay protocol over dissimilar Rayleigh fading channels. The technique of orthogonal space-time block coding (STBC) is applied at the links of source-relay, source-destination and relay-destination. Closedform expressions of outage probability and SER are derived, respectively. Simulation results demonstrate those theoretical solutions.
