数字信道化接收机研究

Study on the Digital Channelized Receiver

首先讲述了接收机的软件无线电结构的设计方案，然后详细分析了A／D转换和实时功率谱估计的设计。最后重点对数字信道化方案进行了分析、推导和设计。

This paper concern a wideband IF electronic warfare (EW) channelized receiver design, the detail of the principle and design method including digital channelization, spectrum estimation and analog-to-digital conversion was presented. Some of the concept and circuits were simulated by Matlab and were proved be true.
