Experiments on Coherent Adaptive Antenna Array Diversity for Wideband DS-CDMA Mobile Radio
Overview In Wideband direct sequence Code Division Multiple Access (W-CDMA), employing an adaptive antenna array is a very promising technique to reduce severe Multiple Access Interference (MAI) from high rate users. A four-antenna Pilot Symbol-Assisted Coherent Adaptive Antenna Array Diversity (PSA-CAAAD) receiver comprising an adaptive antenna array based on a Minimum Mean Squared Error (MMSE) criterion and a Rake combiner is implemented in preliminary laboratory and field experiments. There are two important design concepts of the PSA-CAAAD receiver. This paper presents the effectiveness of PSA-CAAAD receiver as a powerful means to reduce severe MAI from high rate users, and that it is more effective than using a space diversity receiver with the same number of antennas in the W-CDMA reverse link.
