Abstract :
In this paper, we derive an affine projection algorithm (APA) for blind multiuser equalisation, suitable for downlink DS-CDMA systems. Adaptation is performed by minimising a cost function based on the constant modulus (CM) criterion for all users. Computer simulations are used to assess the performance of the algorithm
