Executive Summary

In this paper, a multi - source multi - relay cooperative wireless network with binary modulation and binary network coding is studied. The system model encompasses: a demodulate - and - forward protocol at the relays, where the received packets are forwarded regardless of their reliability; and a maximum - likelihood optimum demodulator at the destination, which accounts for possible demodulations errors at the relays. An asymptotically - tight and closed - form expression of the end-to-end error probability is derived, which clearly showcases diversity order and coding gain of each source.
