Title: SYMBOL RATE ESTIMATION METHOD AND DEVICE
Abstract:
Provided in embodiments of the present application are a symbol rate estimation method and device. The method comprises: performing, according to a first symbol rate of a non-linear modulation signal, decimation on a first baseband signal of a digital signal corresponding to the non-linear modulation signal to obtain a second baseband signal of the digital signal; acquiring, according to the first symbol rate, the second baseband signal, and a carrier frequency offset of the non-linear modulation signal, a second symbol rate of the non-linear modulation signal; and acquiring, according to the first symbol rate and the second symbol rate, a third symbol rate of the non-linear modulation signal. The embodiments of the present application improve accuracy of the acquired third symbol rate of the non-linear modulation signal, thus enabling acquisition of an accurate symbol rate for a non-linear modulation signal.
