摘要：
The performance of adaptive beamforming algorithm using pilot channel that is suitable for the cdma2000 reverse link is evaluated in [1]. It updates the weight vector through the complex normalized least mean square algorithm with the pilot channel, and applies the weight vector to the traffic channel at traffic symbol rate. However, it is degraded by the channel estimation error especially in fading channel. Therefore, we propose a new algorithm using the pilot and traffic channel, which calculates the weight vector more precisely. In addition, the proposed beamforming algorithm has a robust characteristic against channel estimation error. Through the simulation the performance is compared with the method in [1] and evaluated.
