Abstract

This paper concentrates on developing a complexity reduced adaptive space-time interference canceller for multiuser WCDMA forward link. Through exploring the multiuser interference and utilizing the space-time diversity, a sub-optimum diversity receiver, called a reduced-rank constrained adaptive space-time interference canceller (R-CASTIC), is proposed. The proposed scheme mitigates the disadvantages of the full-rank multiple antenna system, such as computational complexity and increased difficulty to accurately tune the algorithm. R-CASTIC performs similar to the full-rank receiver within 1 dB at the BER of 10-3 in less than 60% of total cell capacity, with only an eighth of the complexity of a full-rank receiver.
