摘要：
Smart antennas are widely used for wireless communications due to their ability to increase the coverage and capacity of communication systems. Adaptive algorithm is one of the core technologies of smart antenna. Adaptive beamforming can receive signal from a certain direction by adjusting the array weight vector to enhance the desired signal and suppress the interference and noise. This paper proposes a new adaptive beamforming algorithm by analyzing and improving an algorithm based on projection of gradient vector. We apply this algorithm to a Uniform Linear Array (ULA) and its improved structure to compare its performance with that of the conventional Least Mean Square (LMS) algorithm. Simulation results show the effectiveness of the new algorithm.
