The exact average capacities of rate adaptive single-relay selection decode-and-forward dual-hop relaying for block Rayleigh fading with two cooperation schemes, called parallel channel cooperation and repetition-based cooperation (RC), are obtained. General, dissimilar fading channels and the effect of the source-destination link are considered. Accurate approximations to the average capacity in...
Cooperative relaying introduces spatial diversity through the creation of a virtual antenna array. The vast majority of research in bit-error-rate (BER) performance analysis of selection-combining (SC) schemes used in digital cooperative relaying assumes the modulation level used by both the source and the relay to be the same. This assumption does not necessarily hold when adaptive modulation is...
