Abstract: A transmitter is configured to transmit a radio frequency (RF) signal to a receiver. The receiver is configured to receive the RF signal and decode data. Furthermore, a method of wireless communication is provided between the transmitter and the receiver, in which the transmitter transmits to the receiver the RF signal. A carrier phase of the RF signal is randomly converted. The receiver detects an envelope of the RF signal, and extracts data from the RF signal.
