| 摘 要： | TD-SCDMA系统基站端的智能天线通过波束形成能够显著减小多址干扰,改善通信质量.提出了一种加入扩频序列的协方差矩阵求逆最小二乘恒模(SMI-LSCMA)波束形成算法,该算法在SMI-LSCMA基础上利用特定用户信号的扩频序列信息来锁定该用户接收信号,这样可以使权值向量更新算法更快收敛.经过仿真验证,该算法具有较好的...

| Abstract: | The multi-access interference and quality of communication system can be greatly improved by beam forming when smart antenna is adopted.An improved SMI-LSCMA beam forming algorithm is proposed,in which the spread spectrum sequence of the given user’s signal is used to lock the signal,thus accelerating the convergence of the weight value update algorithm.The simulation experiments show that the algorithm has good ability in beam forming and higher output SNR. |
