Title:
SIGNAL TRANSMISSION METHOD, SIGNAL TRANSMISSION APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123688
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and signal transmission apparatus for use in a scatter communication system, and an electronic device. The scatter communication system comprises a transmitting end and a receiving end. The method is applied to the receiving end, and comprises: the receiving end receiving a test signal transmitted by a transmitting end; extracting a first pilot frequency sequence and a second pilot frequency sequence from the test signal, and performing power calculation on the first pilot frequency sequence and the second pilot frequency sequence to obtain signal-to-noise ratio estimation and receiving level estimation; the receiving end searching a preset mapping relationship table, and determining a target modulation scheme that is matched with fixed power, the signal-to-noise ratio estimation, and the receiving level estimation; and replying a test response to the transmitting end, so as to instruct the transmitting end to perform signal transmission on the basis of the target modulation scheme. According to the present application, the service rate of a communication device in the scatter communication system can be matched with a channel fading condition, so that the reliability of signal transmission of the communication device in the scatter communication system is ensured.
