Embodiment Construction

[0069] Such as figure 1 As shown, the present invention uses a communication method between communication devices using ambient RF wireless charging, using a transmitter S and a receiver D for communication, and the transmitter S can perform an active transmission mode for data or a backscatter transmission for data mode, and RF energy harvesting; the receiver D can demodulate data from modulated backscatter and active RF transmissions;

[0070] The data transmission mode can be completed by the transmitter S by receiving selection signaling;

[0071] The specific communication method includes the following steps:

[0072] The first step is to set the system model of transmitter S and receiver D;

[0073] It is assumed that there are RF signal sources Φ and Ψ in the environment, which are in different frequency bands;

[0074] The transmitter S collects RF energy in the signal source Φ environment;

[0075] When the transmitter S is in the ambient backscatter mode of opera...
