Blind PARAFAC Receiver for Space-Time Block-Coded CDMA System

摘要

An analysis of the received signal of space-time block coded CDMA system shows that the received signal has trilinear model characteristics, and hence blind PARAFAC (PARArallel FACtor) receiver algorithm for space-time block coded CDMA system is proposed in this paper. The proposed PARAFAC receiver capitalizes on antenna, temporal and spread diversity-combining. The simulation results reveal that the performance of blind PARAFAC receiver algorithm for space-time block coded CDMA system is very close to the non-blind maximum likelihood receiver. The PARAFAC receiver does not require channel parameter, so it is blind method.
