Abstract
Embodiments of full duplex radios are disclosed herein. For example, a radio may include: a first transmitter, a second transmitter, and a receiver. The first transmitter may be configured to receive an input signal, process the input signal to generate a first transmit signal, and transmit the first transmit signal. The second transmitter may be configured to receive the input signal, process the input signal to generate a second transmit signal, and couple the second transmit signal into an input path of the receiver. Leakage at the receiver may thus be reduced. Some embodiments of a radio may also include a base band correction circuit and means for reducing transmitter noise that leaks into the receiver.
Claims12
A full duplex radio with reduced noise, comprising:
- a first transmitter;
- a second transmitter, different from the first transmitter;
- a receiver;
- and
- a noise correction circuit;
- wherein:
- the first transmitter is to receive an input signal, process the input signal to generate a first transmit signal, and transmit the first transmit signal,
- the second transmitter is to receive the input signal, process the input signal to generate a second transmit signal, and couple the second transmit signal into an input path of the receiver,
- the noise correction circuit is to generate a correction signal and to couple the correction signal into an output path of the receiver, and
- the input path of the receiver is between a baseband source and the receiver, and the output path of the receiver is different from the input path of the receiver.
