摘要

我们分析了一种解调技术，其中BFSK信号的采样版本通过一个自适应数字陷波滤波器，该滤波器估计并跟踪输入信号的瞬时频率。通过对估计的瞬时频率序列进行平滑处理，然后进行硬决策，得到解调信号。

Demodulation of BFSK signals by adaptive digital notch filtering

We analyze a demodulation technique in which a sampled version of a BFSK signal is passed through an adaptive digital notch filter that estimates and tracks the instantaneous frequency of the incoming signal. By smoothing of the estimated instantaneous frequency sequence followed by a hard decision, we obtain the demodulated signal.
