Title:

BACKSCATTER COMMUNICATION METHOD, EXCITATION DEVICE, REFLECTION DEVICE AND RECEIVING DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/233231

Kind Code:

A1

Abstract:

Disclosed are a backscatter communication method and a related device. The method comprises: an excitation device determining a first sequence and generating a first signal, and sending the first signal, wherein the first signal carries the first sequence; after receiving the first signal, the reflection device modulating reflection device data onto the received first signal to obtain a second signal, and reflecting the second signal so as to realize first scrambling of the reflection device data by the first sequence; and the receiving device determining the first sequence and receiving the second signal from the reflection device, and demodulating the received second signal according to the first sequence to obtain the reflection device data carried on the second signal. By means of the embodiments of the present application, the anti-interference capability of reflection device data can be improved, thereby reducing the continuous interference occurring during a backscatter communication process, and improving the anti-interference capability and network performance of a backscatter communication network.
