Dual-Hop Relaying Communications with Cochannel Interference Over $\eta$ - /spl mu/ Fading Channels

This paper provides an analytical framework for the performance evaluation of dual-hop decode-and-forward (DF) cooperative systems operating over η- μ fading channels in the presence of cochannel interference (CCI) and additive white Gaussian noise (AWGN). The interferers are subject to independent but not necessarily identically distributed η- μ fading. For the considered system, assuming multiple interferers at both the relay and the destination, simple accurate analytical expressions for the outage probability (OP), average bit error probability (ABEP), and average capacity are derived. Various numerically evaluated results accompanied with Monte Carlo simulations are presented to corroborate the accuracy of the proposed approximations.
