Abstract

A new adaptive beamforming method for direct sequence code division multiple access (DS-CDMA) communication systems is proposed, which has low computational load. The proposed method needs only 2N+1 complex multiplications and 2N-1 complex additions, where N is the number of antennas in the array. We evaluate the performance of the proposed method in estimating the angle-of-arrival (AOA) of the desired signal and in producing the array beam pattern. Moreover, the performance of the proposed method in alleviating the probability of bit error in both fading and non-fading channel is verified. It is observed that although the proposed method has low computational load, nevertheless it has desirable performance.

基于特征分解的CDMA通信系统波束形成新算法
提出了一种新的适用于直接序列码分多址(DS-CDMA)通信系统的自适应波束形成方法,该方法具有较低的计算负荷。该方法只需要2N+1次复乘法和2N-1次复加法,其中N为阵列天线数。我们评估了该方法在估计期望信号的到达角(AOA)和产生阵列波束方向图方面的性能。此外,还验证了该方法在降低衰落信道和非衰落信道误码概率方面的性能。结果表明,该方法虽然计算量小,但具有良好的性能。
