1. A signal processing method, comprising:
receiving a first signal;
processing the first signal to obtain a squared complex envelope of the first signal;
obtaining a second signal by processing the squared complex envelope of the first signal using a first filter, wherein a cutoff frequency of the first filter is determined according to an average-to-peak power ratio of a squared complex envelope spectrum of a third signal, the third signal is obtained by processing the first signal using a second filter, and a cutoff frequency of the second filter is determined according to a bandwidth occupied by the first signal;
determining a squared complex envelope spectrum of the second signal; and
determining a symbol rate corresponding to the first signal according to the squared complex envelope spectrum of the second signal.
