Abstract
The disclosed systems and methods are directed to wireless receiver systems for neutralizing the effects of received RF blocking signals. The configurations presented herein operate to receive RF signals containing a desired signal and a blocking signal, a first module, in communication with the receive RF signals along a first signal path and configured to extract a specimen of the received desired and blocking signals, and a second module, in communication with the first module along a second signal path to receive the desired signal and blocking signal specimens. The second module is configured to produce a replica of the blocking signal based on the blocking signal specimen, generate an anti-blocking signal based on the blocking signal replica, and introduce the anti-blocking signal to the received desired and blocking signals in which the anti-blocking signal destructively interferes to neutralize the received blocking signal.
