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.
