Abstract

The invention relates to a signal processing method, electronic equipment and a storage medium, which are applied to the technical field of signal processing, and the method comprises the following steps: obtaining frequency domain characteristics and time domain characteristics of a to-be-identified signal, the frequency domain characteristics comprising the peak number of the spectrum of the to-be-identified signal and/or the gentle degree of spectrum distribution, and the time domain characteristics comprising the peak number of the spectrum of the to-be-identified signal and/or the gentle degree of spectrum distribution; the frequency domain feature comprises a discrete level number of an envelope of the signal to be identified and/or a gentle degree of the envelope, comparing the frequency domain feature and the time domain feature with a preset frequency domain feature and a preset time domain feature of a preset modulation mode to obtain a comparison result, and obtaining the modulation mode of the signal to be identified according to the comparison result. The problem that in the prior art, much prior information is obtained and cannot be accurately obtained, so that an identification result is inaccurate is solved.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a signal processing method, electronic equipment and storage media. Background technique [0002] In communication technology, different modulation methods can be used to improve transmission efficiency, and it is often necessary to identify the modulation type at the receiving end according to the received signal in order to restore the original signal. [0003] In related technologies, the identification algorithm of the modulation method needs more prior information, such as carrier frequency, signal bandwidth, symbol rate, and even synchronization point, etc. However, in engineering practice, third-party monitoring receivers generally can only obtain one The rough carrier frequency and signal bandwidth cannot accurately obtain the above prior information, making the identification result inaccurate. Contents of the invention [0004] The present app...
