Abstract

We consider a cooperative diversity system with a source, a relay and a destination. The relay adopts decode and forward protocol. In this work, we propose a enhanced diversity combining scheme based on the assigned threshold value. Furthermore, We derive the end-to-end symbol error probability of this scheme with M-ary phase shift keying for a slow, flat Rayleigh fading. Numerical results show that the Switched combining scheme performs better than the conventional selection combining

Key Words: (Decode and forward (DF), M-ary phase-shift keying (MPSK), Rayleigh fading, Scaled Selection,, symbol error probability (SEP).
