Title:
MODULATION MODE IDENTIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/082469
Kind Code:
A1
Abstract:
The embodiments of the present application provide a modulation mode identification method and apparatus, relating to the technical field of radio communications. Said method comprises: an electronic device being able to receive a signal to be identified, and determine, according to frequency components and cyclic frequency components of said signal, a cyclic spectrum of said signal and use same as a target cyclic spectrum; and then, input the target cyclic spectrum into a pre-trained modulation mode identification model, so as to obtain a modulation mode of said signal. By means of the present application, the cyclic spectrum of a signal to be identified can be completely inputted into the modulation mode identification model, so as to identify the modulation mode of said signal, that is, the modulation mode of said signal is identified by means of all the features of the cyclic spectrum of said signal, rather than some features of the cyclic spectrum, so that the accuracy of signal modulation mode identification is improved.
