二进制频移键控(2FSK)在电力线载波通信系统中应用广泛。本文提出了一种基于数字信号处理(DSP)时,相位连续2FSK 信号的非相干差分解调方法——单零点FIR 滤波器系数方法,并给出了DSP 实现的结果。关键词 2FSK 信号;非相干差分解调;DSP;时间延迟;FIR 滤波器Abstract: Frequency shift-keying (2FSK) is widely used in power line carrier communicationsystems. In this paper, a new way of the non-coherent differential demodulation for acontinuous-phase 2FSK signal,i.e. a single zero FIR filter coefficient way based on DSP, isintroduced, and the DSP result is presented also.Keywords: 2FSK Signal; Non-coherent Demodulation; DSP; Time Delay; Digital Filtering
