SIGNAL CANCELLATION SYSTEM AND METHOD

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 downconver...

description 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.
