Research on Complex Envelope Extracting Algorithm of Multiple Band-pass Signal

摘要：

After Analyzing the feature of multi-channel signals, we present a digital signal processing algorithm to extract complex envelope of all kinds of pass-band signal. The algorithm keeps the completeness of signal features, reduces the sampling frequency and sampling data, and improves the computation efficiency of real time processing. It can be applied to extract the complex envelope of multi-channel signals.
