一种宽带信号的多速率处理方法

摘要

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 .%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。
