Abstract

The performance of a two-hop amplify-and-forward relay link in flat Rayleigh fading channels is analyzed. Closed-form expressions are obtained for the distribution of the instantaneous signal-to-noise ratio (SNR). An expression for the error probability is presented in general, and the bit-error rate (BER) associated with binary differential PSK (BDPSK) and the symbol-error rate (SER) associated with M-ary amplitude-shift keying (ASK) modulation schemes are derived in particular. These theoretical results are well supported by simulation results. In principle, the analysis approach, which is different from and much simpler than that reported in [9], can be generalized and applied to relay systems that include more hops.
