Outage probability of AF, DF and CF cooperative strategies for the slow fading relay channel

Abstract

We compare in a unified way the outage probability performance of the three cooperative strategies: decode-and-forward (DF), compress-and-forward (CF) and amplify-and-forward (AF). The strategies are treated in the slow Rayleigh fading relay channel under different channel conditions for both full-duplex and half-duplex modes of operation. Perfect channel state information (CSI) is assumed to be available at the transmitter and the relay. The systematic comparison reveals the cases where the use of certain cooperative strategy is beneficial.
