Abstract :
A novel multiple access scheme, referred to as cooperative code division multiple access (CCDMA), is analysed over a AWGN channel. Such a scheme appears to significantly increase the system capacity compared to that of current CDMA systems. This capacity increase is due to the multiple access coding scheme employed. A comprehensive analysis of a cellular wireless network uplink CCDMA architecture employing two-user asynchronous uniquely decodable (ASUD) codes and over an AWGN channel is presented. A noncoherent reception technique ensures that the CCDMA architecture is practical from an uplink synchronization standpoint. Preliminary BER and system capacity assessments are carried out and initial simulation results are presented
