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.
Claims20
A transmitter, comprising:
- a generator configured to convert input data to a pulse;
- a converter configured to randomly change a phase of a radio frequency (RF) oscillating signal;
- and
- a transmitter configured to convert the pulse to an RF signal based on the RF oscillating signal, and transmit the RF signal to a receiver.
A transmitter comprising:
- a data encoder configured to output a quantized result indicative of mapping input data to an element set;
- a converter configured to randomly change a code of the quantized result and output an output signal indicative thereof;
- a pulse shaper configured to convert the output signal to a form of a pulse;
- and
- a transmitter configured to convert the pulse to an RF signal based on an RF oscillating signal and transmit the RF signal to a receiver.
A receiver comprising:
- an envelope detector configured to detect an envelope of a radio frequency (RF) signal;
- and
- a data decoder configured to decode data based on the envelope of the RF signal,
- wherein the RF signal comprises a randomly changed carrier phase.
A method of wireless communication at a transmitter, comprising:
