Abstract: Consider a multi-relay cooperative diversity network consisting of a source, N relays, and a destination. For the transmission of a data symbol from the source to the destination, the re- lays cooperate with the source through the decode and forward protocol. All the links are statisti- cally independent and undergo flat Rayleigh fad- ing. Conventional instantaneous signal-to-noise ratio based selection combining at the destina- tion chooses one link from the set consisting of the source-to-destination link and the N relay-to- destination links. However, this scheme does not account for the effect of the source-to-relay links in the error performance. To overcome this draw- back, we present here a scaled selection combining scheme, which accounts for this effect through a deterministic scale factor. The end-to-end symbol error probability (SEP) of this scheme with binary phase-shift keying is derived in closed form. We also give a method of obtaining the optimum scale factor that minimizes the end-to-end SEP.
