Abstract:
Systems, methods, and circuitries are disclosed for generating a desired signal from a received signal. In one example a signal cancellation system includes local oscillator (LO) downconverter circuitry, frequency offset (FO) signal estimation circuitry, and cancellation circuitry. The LO downconverter is configured to downconvert the received signal using an LO signal having an LO frequency to generate a downconverted received signal. The FO signal estimation circuitry includes FOLO generation circuitry configured to modify the LO signal to generate a FOLO signal having an offset frequency that is different from the LO frequency and FOLO downconverter circuitry configured to use the FOLO signal to downconvert a signal derived from the received signal to generate a downconverted FO signal. The cancellation circuitry is configured to cancel either the downconverted received signal or the downconverted FO signal from the received signal to generate the desired signal.

Claim (Index 12):
The method of  claim 11 , wherein cancelling the downconverted FO signal comprises convolving the FO signal with an estimated phase noise and subtracting the convolution result from the downconverted received signal to generate the desired signal, and wherein the method further comprises determining the estimated phase noise by:\n evaluating a quality of configured to estimate phase noise based at least on a quality of data symbols recovered from the desired signal output by a cancellation circuitry; reconstructing a time domain received signal from the recovered data symbols; and until the quality of the data symbols reaches a threshold:\n estimating noise in the desired signal by subtracting the time domain received signal from the desired signal; and \n calculating a subsequent estimated phase noise based at least on the estimated noise; and \n providing the subsequent estimated phase noise to the cancellation circuitry to generate a subsequent desired signal.
