摘　　要：目前大多数的数字信道化结构多采用均匀信道化方式,信道宽度是固定不可改变的,此时当接收宽带信号时就会存在信道过宽的问题。信道过宽会对信号信噪比的提升造成一定程度的影响。本文在验证了FPGA动态部分重构可行性的基础上提出匹配跟踪滤波器改进了原有的高效数字信道化结构。在保证信号低速处理的同时进一步提升了信号的信噪比。At present,most of digital channelized architectures use uniform channelization mode. The width of channels is fixed. Then,it faces the problem of over wide when receives the wideband signal.This problem affects the increase of SNR. This paper proposed the tracking match filter to improve the original digital channelized architectures based on the verification of FPGA dynamic partial reconfiguration technology. It can improve the SNR and keep the low-speed processing at the same time.
