摘　　要：模拟接收机对硬件依赖性强、信号适应能力差,论文研究的数字接收机是在同一硬件平台上,调用相应的软件解调程序,灵活地实现了多种调制方式的解调功能。论文着重介绍了AM、FM、FSK、CW、SSB(USB/LSB)调制方式的数字解调原理。Analog receiver highly depends on hardware, but it is not good at adapting signal. In this paper, the digital receiver is pro- posed 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）.
