Abstract: The present invention relates to a cooperative spectrum detection method based on backscatter and over-the-air computation. In consideration of a 5G cellular Internet of Things scenario, the method uses widely distributed mobile user equipment as spectrum detection assistants to cooperatively help a requester acquire the current spectrum status. The specific steps are as follows: first, each detection user uses backscatter to directly backscatter a received spectrum signal to a requester as a target, without the need of performing local sensing and data processing procedures; then, by using over-the-air computation, all the spectrum signals backscattered by the detection assistants are reported to the requester through the same backscatter channel, and superposition of the backscattered spectrum signals is achieved by using the accumulation characteristics of a wireless channel; and finally, the requester performs sampling analysis on the received over-the-air merged spectrum signal to make a final spectrum detection determination.
