Distributed coded cooperative with AF relaying for three different Protocols

Abstract

This paper considers a scheme of distributed coded cooperation for three different Protocols where the antennas are shared between source and relay so that an array for virtual transmission is created to facilitate transmission towards the destination. Since the relaying employed by relay uses amplify-and-forward (AF). The source is assumed to be equipped with two encoders, where the first one output is known as the first frame and the second one output of is known to as the second frame. A distributed coded cooperation for the three Protocols is analyzed. Specially, upper bounded expressions for the bit error rate is derived assuming binary phase shift keying (BPSK) transmission. The analytical results obtained show that the maximum diversity order of all the Protocols is maintained for the entire range of bit error rate of interest, unlike the case with no cooperation. Several numerical and simulation results are presented to demonstrate the efficacy of the distributed coded cooperation scheme for three Protocols.
