Large System Performance Evaluation of the DS/CDMA Relay Channel Using Linear Receivers

— This paper considers a relay communication system where cooperative diversity is achieved by spreading the relay transmissions using direct-sequence CDMA (DS/CDMA). We derive expressions for the signal to noise ratio (SNR) employing different receiver filters. The relay signatures are generated according to a random model and the SNR is evaluated in the asymptotic domain, assuming that the number of relays and the signature length grow without bound but with constant ratio.
