Abstract
Disclosed herein are methods and systems for canceling a blocking signal to obtain a desired signal. An example process includes receiving both a blocking signal and a set of blocking bits corresponding to a demodulation of the blocking signal. A remodulated blocking signal is generated by modulating the received set of blocking bits. The remodulated blocking signal is passed through a blocking-band bandpass filter to generate an estimated blocking signal, and is also passed through a desired-band bandpass filter to generate an unconditioned reference signal. One or more signal-parameter differences between the blocking signal and the estimated blocking signal are identified, and one or more signal compensations are accordingly applied to the unconditioned reference signal to generate a conditioned reference signal, which is then output to a blocking-signal-canceling system.
