Patent ID: 8433015

Claim:
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 unwanted inband signals wherein the power of the desired received communication signal is greater than the aggregate received power of the inband signals; and a signal processor that processes the received signal to form an estimate of the desired communication signal and an estimate of the inband signals and thereby removes the estimate of the inband signals from the received signal, wherein the signal processor forms the estimate of the desired communication signal by demodulating the received signal to form a demodulated signal and by remodulating the demodulated signal to form the estimate of the desired communication signal, wherein the signal processor uses the greater power of the desired communication signal to lock to the desired communication signal to form the demodulated signal, and wherein the signal processor forms the estimate of the desired communication signal and the estimate of the inband signals without prior knowledge of characteristics of the inband signals and without obtaining a copy of any of the inband signals from any source other than the received signal.
