Abstract :
In this paper, we give an investigation on the performance of cellular dual-hop cooperative communication systems with regenerative relays over flat Rayleigh fading channels. M-ary phase-shift keying (M-PSK) is considered. Two linear diversity reception techniques are adopted in the destination, i.e.,maximal-ratio combining (MRC) and selection combining (SC).We first derive the symbol error rate (SER) expression of dual hop communication with MRC scheme and all relays randomly distributed between the source and the destination. We then derive asymptotic SER expression. With the aid of the a symptotic analysis, asymptotic-optimal power allocation(A-OPA) strategy provides more significant performance improvement compared to equal power allocation (EPA) strategy. Next, we analyze the performance and the asymptotic performance of dual-hop communication with SC scheme.
