Abstract

The application discloses a carrier signal processing method and device and a storage medium. The carrier signal processing method comprises the following steps: acquiring a carrier signal to be processed, wherein the carrier signal includes multiple wavelet signals; determining the first number of wavelet signals corresponding to each preset frequency band in a plurality of preset frequency bands; determining a demodulation frequency from the preset frequency band with the largest first number; and performing a demodulation operation on the carrier signal by the demodulation frequency in order to locate the carrier frequency accurately. Thus, the digital signal wave is better restored, and the distortion is low. The method is simple.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a carrier signal processing method, device and storage medium. Background technique [0002] In communication technology, a carrier wave is an electric wave generated by an oscillator and transmitted on a communication channel, which is the physical basis and carrying tool for transmitting information. [0003] Since the terminal circuit usually only processes and generates digital signals, and the frequency of the digital signal itself is low, it is not conducive to transmission to the outside world. Therefore, if the terminal wants to transmit the digital signal to the outside world, the digital signal needs to be loaded on a high-frequency carrier (commonly known as modulation process), and transmit to the outside world through the carrier. However, in addition to the digital signal on a carrier, there may be multiple other signals. These other signals ma...
