Abstract
Embodiments of this application disclose a backscatter communication method and a related apparatus. The method includes: receiving, by a backscatter device, a first signal from an excitation device, the first signal carries a first sequence determined by the excitation device; modulating, by the backscatter device, backscatter device data to the first signal to obtain a second signal, wherein the backscatter device data is scrambled by the first sequence; backscattering, by the backscatter device, the second signal to a receiving device.

A method, comprising:
- receiving, by a backscatter device, a first signal from an excitation device, wherein the first signal carries a first sequence determined by the excitation device;
- modulating, by the backscatter device, backscatter device data to the first signal to obtain a second signal, wherein the backscatter device data is scrambled using the first sequence;
- and
- backscattering, by the backscatter device, the second signal to a receiving device.
An apparatus, comprising:
- at least one processor in communication with a memory storing instructions, the at least one processor configured, upon execution of the instructions, to perform operations including:
- receiving a first signal from an excitation device, wherein the first signal carries a first sequence determined by the excitation device;
- modulating backscatter device data to the first signal to obtain a second signal, wherein the backscatter device data is scrambled using the first sequence;
- and
- backscattering the second signal to a receiving device.
A communication system, comprising:
- a backscatter device and an excitation device;
- wherein:
- the excitation device is configured to:
- send a first signal to the backscatter device, wherein the first signal carries a first sequence determined by the excitation device;
- and
- the backscatter device is configured to:
- receive the first signal;
- modulate backscatter device data to the first signal to obtain a second signal, wherein the backscatter device data is scrambled using the first sequence;
- and
- backscatter the second signal to a receiving device.
