Abstract :
In this paper, we study the issue of optimally detecting symbols for a Selective-Decode-and-Forward (SDF) relay-assisted communication system in the presence of channel estimation error for flat Rayleigh fading channels. In the system studied, a pilot symbol-assisted modulation (PSAM) scheme is used along with a channel estimation scheme based on minimum mean square error (MMSE) criterion. In particular, we present a novel spectrum detection in presence of channel estimation error for the SDF protocol. Numerical simulation results are presented to show that the presented spectrum detection scheme performs well in terms of bit error probability (BEP).
