Abstract

In this paper, we derive a fast converging concurrent affine projection algorithm for blind multiuser equalisation, suitable for downlink {DS}-{CDMA} systems. {A}daptation is performed by concurrently minimising two cost functions based on either a {CM} criterion or a {DD} scheme for all active users. {C}oncurrent schemes are known to provide faster convergence. {S}imilarly, affine projection algorithms have been incorporated into blind algorithms elsewhere with good improvement of convergence speed. {I}n the work presented here, we derive a system relying on both principles. {W}e show by computer simulation that substantial performance improvement can be gained over either technique in its own.
