Abstract:
1. A system for removing one or more inband signals from a received communication signal comprising: a receiver that receives a signal that includes a desired communication signal and one or more inband signals; a signal processor that processes the received signal to form an estimate of the desired communication signal and an estimate of the inband signals, wherein the signal processor demodulates the received signal to form a demodulated signal and remodulates the demodulated signal to form the estimate of the desired communication signal and wherein the signal processor performs adaptive noise cancellation on the received signal using the estimate of the desired communication signal to form the estimate of the one or more inband signals; and a performance improver that processes the received signal and the estimate of the one or more inband signals to form an improved estimate of the desired communication signal and an improved estimate of the inband signals, wherein the performance improver comprises an adaptive filter that takes as input the received signal and the estimate of the one or more inband signals to form the improved estimate of the desired communication signal and the improved estimate of the inband signals.
