Abstract:
1. A device for use with a transmission signal generator operable to generate a transmission signal and an antenna operable to transmit a transmit signal and to receive a reception signal, said device comprising: a first transmitter operable to generate an output signal based on the transmission signal; a second transmitter operable to generate a cancellation signal; a duplexer operable to receive a first signal, to receive a second signal, to separate the second signal from the first signal and to generate a duplexed signal, the first signal being based on the output signal and the second signal being based on the reception signal; a combiner operable to combine a third signal and a fourth signal and to generate a received signal, the third signal being based on the cancellation signal and the fourth signal being based on the duplexed signal; a first receiver operable to receive a fifth signal based on the received signal; and a second receiver in communication with said second transmitter and operable to receive a sixth signal and to generate a control signal, the sixth signal being based on the received signal, wherein the cancellation signal is based on the control signal, and wherein a portion of the received signal includes interference based on the first signal.
