1. A remote wireless charging transmit end configured to wirelessly charge a receive end, the transmit end comprising:
a transmit end processor configured to generate a composite signal based on a control signal and a power signal, and send the composite signal to a fundamental frequency-radio frequency conversion unit, wherein the control signal is used to control a working status of the receive end, and the power signal is used to charge the receive end, wherein the transmit end processor is further configured to: generate a phase-modulated signal based on the control signal, and generate the composite signal based on the phase-modulated signal;
the fundamental frequency-radio frequency conversion unit configured to convert the composite signal into a radio frequency signal, and send the radio frequency signal to a transmit end antenna; and
the transmit end antenna configured to transmit the radio frequency signal corresponding to the composite signal.
