摘要
介绍了相位连续频移键控系统相干解调原理,并重点推导了解调时所需同步载波的几种产生方法和电路结构,为通信系统提高抗噪性能提供了条件。
The paper introduces the principles of continuous-phase frequency shift keying demodulation. The writer puts stress on the realizations of coherent for demodulation, as well as the constructions of circuit. It improves the resisting noise property of communication system.
