Claim Text:
1. A receiver system comprising: an input configured to receive an input signal; a signal generating circuit configured to generate a desired oscillator signal that is a single sideband radio frequency (RF) signal, wherein an oscillation frequency of the desired oscillator signal shifts over time; a downconversion stage configured to generate an intermediate frequency (IF) signal based on the input signal and the desired oscillator signal; and a signal processing block configured to produce an output signal based on the IF signal, wherein in generating the output signal, the signal processing block is configured to track any signal in the IF that moves one-for-one in frequency with the desired oscillator signal by frequency shifting receive data corresponding to the IF signal by an amount that compensates for a shift of the oscillation frequency of the desired oscillator signal.
