摘要
主要是以DS-CDMA系统中智能天线技术为研究背景。首先介绍了LS-DRMTCM算法和DR-LMS算法,然后提出了一种变步长的码滤波波束形成算法。仿真结果表明:新算法在简化计算的基础上,和原算法有相近的跟踪性,同时收敛性能有明显的改进。
The main context of this paper is beamforming algorithm on smart antenna tecb.nique of DS-CDMA system. The LS-DRMTCM algorithm and DR-LMS algorithm are first introduced, then a variable step-size PN cold filter adaptive beamforming algorithm is presented. Simulation results show that the track performance of new algorithm with small computing complexity is similar to the former algorithms, and its convergence has a great improvement.
