Abstract

Relaying communications has been proposed as a way to provide spatial diversity. In general, one is interested in a relaying system that can achieve the maximal diversity order with a low system complexity. One enabling technique is equal gain combining (EGC) and its application in relaying systems is the main focus of this paper. In particular, the techniques of EGC and smart relaying are combined in the decode-and-forward (DF) processing method. It is shown that for a system with one relay and M-ary phase-shift-keying (M-PSK) modulation, maximal diversity orders of 2m and 2 are achieved over Nakagami-m and Hoyt fading environments, respectively. With K relays, simulation results suggest that the corresponding diversity orders are m(K + 1) and (K + 1).
