Title:
SIGNAL PROCESSING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/104807
Kind Code:
A1
Abstract:
Disclosed are a signal processing method and apparatus. The method comprises: receiving a first signal; processing the first signal to obtain a square complex envelope of the first signal; processing the square complex envelope of the first signal by using a first filter to obtain a second signal, a cut-off frequency of the first filter being determined according to a power ratio of a square complex envelope spectrum mean value to a peak value of a third signal, the third signal being obtained by processing the first signal by using a second filter, and a cut-off frequency of the second filter being determined according to a bandwidth occupied by the first signal; determining a square complex envelope spectrum of the second signal; and according to the square complex envelope spectrum of the second signal, determining a symbol rate corresponding to the first signal. By implementing the embodiments of the present application, accurate determination of the symbol rate of the signal is achieved.
