DS-CDMA系统自适应天线波束形成技术及波达方向估计方法研究
A Modified Algorithm of DOA Estimation and Adaptive Beamforming for DS-CDMA Systems
【摘要】 基于空间变步长搜索算法提出了一种适用于DS CDMA系统的自适应波束形成及波达方向估计的改进算法。由于利用了DS CDMA系统已知用户扩频码这一特点,因此算法的正确率更高。理论分析和仿真结果证明了该算法的正确性。
【Abstract】 Based on spatialvaried stepsearch method,a modified algorithm of DOA estimation and adaptive beamforming for DSCDMA systems is presented.The Algorithm is higher in correct rate because of the utilization of known spreading mode in the DSCDMA systems.The algorithm is verified by the result of theoretical analysis and computer simulation.
