Abstract:
A method for Tx interference cancellation and power detection in a wireless device is described. A portion of a Tx output signal is down-converted to generate a feedback signal. A reconstructed interference signal and a weight are generated based on the feedback signal. A Tx power level is detected based on the weight. The reconstructed interference signal is subtracted from the Tx output signal.
