Communication system, communication method, communication device, communication equipment, storage medium and product

The invention relates to a communication system, a communication method, a communication device, communication equipment, a storage medium and a product. The communication system comprises a signal source, a backscattering label, a receiving end and an eavesdropping end, wherein the signal source is used for transmitting a radio frequency signal; the backscattering tag is used for sending the radio frequency signal and the interference signal; the receiving end is used for receiving the combined signal and identifying a radio frequency signal from the combined signal; the combined signal comprises a radio frequency signal and an interference signal; and the eavesdropping end is used for receiving the combined signal. Therefore, in the communication system provided by the embodiment of the invention, the interference signal is manually sent while the radio frequency signal is sent through the backscattering tag, so that the signal-to-noise ratio of the radio frequency signal received by the eavesdropping end i
