A method and an apparatus for estimating symbol rate of frequency shift based modulation signals

摘要

According to some embodiments, a method of receiving a frequency shifted digital modulation signal, obtaining in-phase / quadature (I / Q) data from the frequency shifted digital modulation signal, and using the obtained I / Q data Estimating a bandwidth of the modulated signal; Oversampling the obtained sampling rate of the obtained I / Q data to a value equal to or greater than 8 times the estimated bandwidth, and using the oversampled I / Q data to obtain a symbol rate of the frequency-varying digital modulation signal. A method of estimating is disclosed.
