Abstract
Disclosed is a self-correlation receiver of a transceiver in which a transmitter shares an antenna with a receiver. The self-correlation receiver includes: a clamper which receives a received signal, limits the magnitude of the received signal within a predetermined range and outputs a clamping signal; and a mixer which receives the received signal and the clamping signal and outputs a signal having a difference frequency between the received signal and the clamping signal.
Claims13
A transceiver comprising:
- an antenna;
- a transmitter;
- and
- a receiver comprising a self-correlation receiver, wherein the self-correlation receiver comprises:
- a clamper which configured to receive a received signal comprising a first signal from the transmitter and a second signal from the antenna, limit the magnitude of the received signal within a predetermined range, and output a clamping signal which is substantially the same as the first signal;
- and
- a mixer configured to receive the received signal and the clamping signal, and output a signal corresponding to an envelope signal of the second signal and having a difference frequency between the received signal and the clamping signal.
A quadrature transceiver in which a transmitter shares an antenna with a first self-correlation receiver and a second self-correlation receiver, the quadrature transceiver comprising:
- a phase shifter configured to shift the phase of an input signal;
- the first self-correlation receiver;
- and
- the second self-correlation receiver,
- wherein the first self-correlation receiver comprises:
- a first clamper configured to receive a first received signal comprising a first transmitter signal from the transmitter that has passed through the phase shifter and a first antenna signal from the antenna, limit the magnitude of the first received signal within a predetermined range, and output a first clamping signal;
- and
- a first mixer configured to receive the first received signal and the first clamping signal, and output a first output signal having a difference frequency between the first received signal and the first clamping signal, and
- wherein the second self-correction receiver comprises:
- a second clamper configured to receive a second received signal comprising a second transmitter signal from the transmitter and a second antenna signal from the antenna that has passed through the phase shifter, limit the magnitude of the second received signal within a predetermined range, and output a second clamping signal;
- and
- a second mixer configured to receive the second received signal and the second clamping signal, and output a second output signal having a difference frequency between the second received signal and the second clamping signal.
A self-correlation receiver of a transceiver, the self-correlation receiver comprising:
- a clamper configured to receive a received signal comprising a first signal from a transmitter of the transceiver and a second signal from an antenna of the transceiver, limit the magnitude of the received signal within a predetermined range, and output a clamping signal which is substantially the same as the first signal;
- and
- a mixer configured to receive the received signal and the clamping signal, and output a signal corresponding to an envelope signal of the second signal and having a difference frequency between the received signal and the clamping signal.
