Abstract

We consider a binary asynchronous hybrid SFH/DS-CDMA system with error-control coding on AWGN channels. We assume the case of transmitters of unequal powers and random time-varying signature sequences. Two systems are studied, one with the classical “single user” receiver, and one with a multiuser “projection receiver”. For both, we analytically investigate the trade-off between channel coding and signature sequence spreading to optimise the use of the available processing gain
