Abstract

In this paper, we derive a concurrent constant modulus algorithm (CMA) and decision directed (DD) scheme for blind multiuser equalisation, suitable for downlink DS-CDMA systems. Adaptation is performed by concurrently minimising two hybrid cost functions based on either a CM criterion or a DD scheme for all active users and a mean square error (MSE) criterion for inactive ones. Computer simulations are used to assess the performance of the algorithm
