SIGNAL TRANSMISSION METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2022/165842

A1

The embodiments of the present application relate to the technical field of communications. Provided are a signal transmission method, an electronic device, and a storage medium. The method comprises: adjusting an impedance of a second transceiving link at multiple different moments; when the second transceiving link has multiple different impedances, receiving multiple first carrier signals sent by a first electronic device; on the basis of the multiple first carrier signals received by a second electronic device and the multiple impedances, determining a mapping relationship between phase deviations and impedances; determining the current phase deviation on the basis of the current impedance of the second transceiving link and the mapping relationship; and performing phase compensation on a second modulated signal on the basis of the current phase deviation, and sending to the first electronic device the second modulated signal obtained after the phase compensation. According to the method provided by the embodiments of the present application, the phase of a sent signal is compensated for at an NFC terminal, so that a phase deviation between a card reader signal and an NFC terminal signal can be eliminated, thereby improving the signal demodulation efficiency of a card reader.
