Claim:
1. A system for removing one or more unwanted inband signals from a received communication signal comprising: a signal attenuator configured to receive a composite signal that includes a desired communication signal and one or more unwanted inband signals, wherein the signal attenuator is configured to selectively attenuate the one or more unwanted inband signals to form a modified received signal that includes the desired communication signal and the attenuated inband signals and further wherein the signal attentuator is configured to selectively attenuate the unwanted inband signals based on the unwanted inband signals being correlated with a delayed version of the unwanted inband signals; and a signal separator configured to process the modified received signal to form an estimate of the desired communication signal and an estimate of the attenuated inband signals, wherein the signal separator performs adaptive noise cancellation on the modified received signal using the estimate of the desired communication signal to form the estimate of the one or more unwanted inband signals.
