Abstract

In this paper, we derive a closed-form expression of approximate average symbol error rate (SER) of a low complexity piecewise linear (PL) decoder in the decode-and-forward (DF) cooperative communication system utilizing M-QAM constellation. The performance analysis is carried out by using the nearest neighbor approach. It is analytically shown by using the derived SER that the PL decoder in a DF based cooperative system with one source-destination pair and a single relay, achieves full diversity of two.
