Abstract:
This invention relates to a system and method for processing signals in a signal processing system so as at least to ameliorate spurious signals generated in said signal processing system during processing of signals. The method, which is implemented by the system in accordance with the invention, typically comprises receiving a signal of unknown and arbitrary frequency within the operating frequency range of the signal processing system, wherein the input signal comprises at least a fundamental signal. The method then comprises generating, in one signal processing path, a compensation signal with same amplitude and phase as the spurious signal. The compensation signal is then subtracted from the received input signal or added out of phase to the received input signal, in another signal processing path. In this way, the spurious signal is cancelled from the received signal and/or the received signal is pre-distorted to account for spurious signals generated during further processing in the signal processing system.

Claim (Index 2):
A method as claimed in  claim 1 , wherein the method further comprises a prior step of characterising spurious signals to be cancelled by:\n determining a frequency relationship between the spurious signal generated by the processing of a signal by the processing system and a fundamental signal associated with the said signal processed by the processing system; determining an amplitude and phase relationship between the spurious signal and the fundamental signal; generating the non-adaptive time-invariant phase and amplitude adjustment filter in the form of a wideband FIR (Finite Impulse Response) filter by using the determined amplitude and phase relationship, wherein filtering a received signal with the generated phase and amplitude adjustment filter scales same to approximately the same amplitude and phase as the spurious signal.
