Abstract

In this paper, we derive the end-to-end (e2e) Bit Error Probability (BEP) of cooperative Multi Carrier Code Division Multiple Access (MC-CDMA) systems using selective threshold digital relaying (STDR). In STDR, a set of potential relays whose received Signal-to-Noise Ratio (SNR) exceeds a threshold value γ_t, called reliable relays, is formed. Then, only the best relay among reliable relays is allowed to retransmit the received signal. We activate the relay with the largest SNR in relay-destination link. The derived BEP results are valid for any multipath intensity profile of the channel.
