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．()

该电子书是用MATLAB语言对数值分析进行描述的。例如：矩阵运算，矩阵分解，微分方程求解，函数插值，函数拟合等数值问题。另外对MATLAB绘图进行了一定的介绍。(The book is a numerical analysis using MATLAB language to describe. For example: matrix operations, matrix decomposition, differential equation solving, function interpolation, function approximation and other numerical problems. In addition to the MATLAB graphics, which must be introduced.)
