This paper presents an adaptive space-time RAKE receiver for WCDMA Uplink.Two matched filters are designed.Based on the maximum signal-to-interference plus noise criterion,a RLS algorithm is used for updating the beamforming weight vectors for each multipath of the desired signal.The scheme proposed can reduce the computational complexity remark-ably and thus lead to fast convergence.Simulation shows that the scheme has the ability of suppressing multiuser access interference(MAI),combating near-far problems,and tracking the channel condition under the fast fading environment.
