Abstract:
1. A device comprising: a transmit chain operable for receiving an input comprising a first digital form of a first signal and for converting the first digital form of the first signal into an analog form of the first signal; a receive chain; and a cancellation block coupled to the receive chain and the transmit chain, wherein the transmit chain is further operable for transmitting the analog form of the first signal while a second signal is being received by the receive chain in a frequency band that overlaps a frequency band used for transmitting the first signal, wherein the cancellation block is operable for generating a third signal that accounts for interference between the first signal transmitted by the transmit chain and the second signal received by the receive chain, wherein a digital form of the third signal is generated using the first digital form of the first signal that is input to the transmit chain, a second digital form of the first signal that was converted from the analog form of the first signal, and a digital form of the second signal, converted from an analog form of the second signal received by the receive chain, and wherein the receive chain is operable for applying the third signal to the second signal received by the receive chain to produce a compensated second signal.
