Abstract :
The performance of linear MMSE multiuser receivers in a dual-rate synchronous DS-CDMA system is investigated using the effective interference and effective bandwidth methodology first proposed by Tse and Hanly (see IEEE Trans. Inform. Theory, vol.45, no.2, 1999). Both multi-code (MC) systems and variable spreading length (VSL) systems are studied. User capacity regions are obtained for these systems
