| Abstract: | An adaptive blind beamforming algorithm for uplink in DS-CDMA system is proposed in this paper. Spatial and temporal joint processing is employed by combining this algorithm with Rake receiver technology. We present a kind of block diagram of 2-D Rake receiver as well. Computer simulation demonstrates that this algorithm can estimate the steering vector of the desired signal rapidly. The algorithm exhibits excellent tracking capability when the DOA of the desired signal is variable. |
