Blind Adaptive Multiuser Detection Based on Affine Projection Algorithm

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 27)


We introduce an algorithm for blind adaptive multiuser detection of synchronous direct sequence code division multiple access (DS-CDMA) signals. This algorithm is based on the affine projection algorithm (APA). We first derive the algorithm for a single antenna at the receiver and then generalize it to the multiple antenna case at the receiver. Simulation results show that the proposed algorithm has lower misadjustment, an improved convergence rate, and superior bit error rate performance compared to existing conventional methods.
