Tight bounds for the
Shannon capacity
of amplifyandforward
cooperative diversity
networks are derived for three different adaptive source transmission policies in a myriad of fading environments: (i) constant power with optimal
rate adaptation
(ORA); (ii) optimal joint power and
rate adaptation
(OPRA); and (iii) fixed rate with truncated channel inversion (TCIFR). Our unified framework based on the momentgenerating function (MGF) approach allows us to gain insights as to how fade distributions and dissimilar fading statistics across the distinct communication links will affect the Shannon capacity, without imposing any restrictions on the fading parameters.
