摘要
本文介绍了下变频的基本原理,以及如何利用下变频器HSP50216对不同的调制信号进行解调,并给出了一个接收系统设计方案,利用HSP50216具有四个独立可编程通道的特点和相位自适应解调原理,实现针对发送端的变化的自动化接收。
This article includes the basic theory of down-conversion and makes an introduction on how to demodulate different kinds of modulated signals by the use of digital downconverter, HSP50216. Besides, with the supports of the feature that HSP50216 has four independently programmable downconverter channels and the theory of automatic identification of modulation modes, the article also gives a design of a receiving system which can finish the receiving process automatically according to the changing of the sender.
