本文提出在数字移动通信中子带滤波器组处理可以提高不同阵元信号的相关性，从而能改善自适应阵列抑制码间干扰(ISI)和共信道干扰(CCI)的能力．在文[6]的基础上，本文研究了子带滤波器组在宽带自适应天线旁 瓣相消中的应用，对其原理进行了理论分析，提出了有效的子带处理方法．经研究表明，子带滤波器组处理能有效增加主、辅助天线信号的相关性，从而提高系统干扰相消比．而且适当的过采样能使系统干扰相消比进一步提高．计算机仿真结果和实测雷达数据处理结果证实了子带处理方法的有效性和理论分析的正确性．()

最小均方（LMS）自适应算法就是一中已期望响应和滤波输出信号之间误差的均方值最小为准的，依据输入信号在迭代过程中估计梯度矢量，并更新权系数以达到最优的自适应迭代算法。LMS算法是一种梯度最速下降方法，其显著的特点是它的简单性。这算法不需要计算相应的相关函数，也不需要进行矩阵运算。(Minimum mean-square (LMS) adaptive algorithm is that one has to respond to the expectations and filtering the output signal of the mean square error between the value of the minimum-based, based on the input signal is estimated in the iterative process of gradient vector, and to update the weights in order to achieve the most Adaptive iterative algorithm gifted. LMS algorithm is a steepest descent gradient method, and its significant features is its simplicity. This algorithm does not require calculation of the corresponding correlation function, nor the need for matrix calculation.)
