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 1):
A method for processing a signal in a signal processing system, wherein the method comprises:\n receiving a signal of unknown and arbitrary frequency within the operating frequency range of the signal processing system, wherein the received signal comprises a fundamental signal; simultaneously digitally processing the received signal in at least two parallel signal processing paths, a first signal processing path and a second signal processing path, respectively; generating, in the second signal processing path, a compensation signal by filtering the received signal with a non-adaptive time-invariant phase and amplitude adjustment filter associated with a characterised spurious signal generated in the signal processing system in processing a signal, and processing the filtered signal to correspond substantially to the frequency of the spurious signal, wherein the compensation signal is a replica of the spurious signal; and subtracting the generated compensation signal from the received signal, or adding the generated compensation signal out of phase to the received signal, in the first signal processing path so as to cancel the spurious signal generated in the processing system thereby yielding a compensated signal.
