基于并行A/D结构的软件无线电中频接收机

Software Radio Intermediate Frequency Receiver Based on the Parallel Analog-to-digital Structure

针对软件无线电技术对A/D带宽要求较高的问题,提出一种新型的基于并行A/D采样结构的软件无线电接收机模型,并对模型各部分的功能进行了深入分析。仿真结果表明,各项指标均满足预期的中频接收机的整体指标,且接收灵敏度较高,从而验证了该模型的可行性。

Aimed at the problem of the demanding requirement of software radio to A/D bandwidth, a new type of software radio receiver pattern is presented based on paralleling A/D sampling structure, and has a deep analysis of the functions of all its parts. As the result of the simulated tests turns out, all the items meet the anticipated indexes of intermediate frequency receiver unexceptionally and with a high receiving sensitivity, which proves the feasibility of this pattern.
