） Abstract： This paper presents an investigation on dual-hop cooperative communication systems with regenerative relays over flat Rayleigh fading channels
Potentially relay nodes which can successfully decode the signals cooperatively relay to destination for performance improvement
Maximal-ratio combining (MRC) reception technique is adopted
M-ary phase-shift keying (M-PSK) modulation is evaluated
We first derive symbol error rate (SER) expression of dual-hop communication with MRC scheme
We also derive asymptotic SER expression
With the aid of the asymptotic analysis, asymptotic-optimal power allocation (A-OPA) strategy is determined
It is shown that a significant performance improvement is achieved compared to that of equal power allocation (EPA) strategy
Keywords： Cooperative communication, dual-hop, maximal-ratio combining
