摘　　要：相比于逐个信道接收的窄带信号而言,宽带接收机具有全概率接收的优势。为了解决接收宽带信号所需要的模/数(A/D)转换采样率高、后续信号处理设备速度慢的问题,讨论了如何在A/D高速采样后使用多种滤波器级联的方法来进行多速率处理,最终达到降速率的目的。Comparing with the narrowband signals received by the channels one by one, the broad band receiver has the advantage of full-probability reception. To solve the problems that the analog to digital （A/D） conversion sampling rate required by receiving broad band signal is high and the velocity of follow-up signal processing devices is slow, this paper discusses how to use multi-filter cascade method to perform multi-rate processing after A/D high-speed sampling,finally achieve the aim of reducing velocity.
