Digital Demodulation Technology for the Base Band Signal

Yang Chunshu

Abstract

Analog receiver highly depends on hardware,but it is not good at adapting signal.In this paper,the digital receiver is proposed based on the same hardware platform,software demodulation process,it shows kinds of flexible modulation demodulation functions.This paper focuses on the principle of the digital demodulation of AM,FM,FSK,CW,SSB(USB/LSB).
