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。
English Description：
In this paper, it is proposed that subband filter bank processing in digital mobile communication can improve the correlation of signals of different array elements, so as to improve the ability of adaptive array to suppress inter symbol interference (ISI) and common channel interference (CCI). Based on [6], this paper studies the application of subband filter bank in broadband adaptive antenna sidelobe cancellation, and makes a theoretical analysis on its principle, An effective subband processing method is proposed. The research shows that subband filter bank processing can effectively increase the correlation of main and auxiliary antenna signals, The computer simulation results and measured radar data processing results confirm the effectiveness of the subband processing method and the correctness of the theoretical analysis
