Abstract :
In this letter, we derive a piecewise linear (PL) decoder of the double differentially modulated symbols in the decode-and-forward protocol based cooperative communication system. The analytical average bit error rate (BER) of the proposed PL decoder is derived. Based on this BER expression, diversity order of the PL decoder is obtained.
