ABSTRACT:
Methods and apparatus describe techniques for reducing interference signals in a communication signal. A communication signal is received through a receiver. The communication signal contains an interference signal. A digital replica of the interference signal is generated, the digital replica is converted into a corresponding analog replica of the interference signal. The analog replica of the interference signal is subtracted from the communication signal.
