Demodulation method and apparatus

摘要

A demodulation circuit and method are provided. The demodulation circuit includes a transformation circuit which is configured to transform the received signal into a modified signal representation in which both amplitude-varying information and frequency-varying information are converted to a uniform representation; and a processing circuit which is configured to process the modified signal representation to demodulate the received signal based on the uniform representation. The method includes transforming the signal into a modified signal representation in which both amplitude-varying information and frequency-varying information are converted to a uniform representation; and processing the modified signal representation to demodulate the signal based on the uniform representation.
