摘要
提出了基于小波包的调频波解调方法 ,通过对各种调频信号进行时频分析 ,给出了信号的时间—频率谱图 ,能有效地检测到瞬时频率和获取调频信息 。
A software method of frequency\|modulated signal demodulating based on wavelet packet is proposed in this paper.A variety of frequency\|modulated signals are analyzed in time\|frequency domain and the spectrograms are presented.This method can detect instantaneous frequency effectively and get frequency\|modulated information,can be widely applied to dynamic testing and software radio.
