摘　　要：数字信道化技术广泛用于宽带信号处理领域,传统的信道化结构由于信道数和抽取(内插)数相等,相邻信道存在混叠问题,对于跨信道信号接收、重构存在很大程度失真。提出一种改进的信道化结构,推导了相应的多相滤波高效算法,最后通过Matlab仿真验证该算法具有很好的改进效果。Digital channelized technique is widely applied on the wide- band signal processing area. As the number of channels equals to the decimating factor( also inserting factor),classic channelized structure has to face the aliasing issues from the overlapping channels,which employs great distortion for the wide- band signal receiving and reconfiguration. An improved channelized structure is proposed,which also deduces the poly- phase filter banks algorithm. Finally the simulation by Matlab shows the method has an excellent result.
