System linearization assembly and method for use in modifying distortion components

A signal processing system comprising:

• a signal modifying device that is configured to receive a signal from a signal source and to modify the signal to generate a modified output signal, wherein the modified output signal includes a time varying parameter representing a plurality of frequency components including at least one component caused by non-linear intermodulation distortion;
• and
• a system linearization assembly coupled to said signal modifying device, wherein said system linearization assembly comprises:
• a filter configured to:
• couple to an output bias tee;
• receive the modified output signal;
• and
• isolate at least one harmonic of the plurality of frequency components with the same order as the at least one component caused by non-linear intermodulation distortion, wherein the isolated at least one harmonic is substantially proportional to the at least one component caused by non-linear intermodulation distortion;
• a measuring device coupled to said filter, wherein said measuring device is configured to determine a measurement of at least one parameter of the isolated at least one harmonic;
• and
• a controller coupled to said measuring device, wherein said controller is configured to modify the signal from the determined measurement to facilitate a modification of the at least one component caused by non-linear intermodulation distortion.

A method for modifying distortion components, said method comprising:

• receiving a signal that includes a time varying parameter representing a plurality of frequency components including at least one component caused by non-linear intermodulation distortion, via a filter that is configured to couple to an output bias tee;
• isolating at least one harmonic of the plurality of frequency components with the same order as the at least one component caused by non-linear intermodulation distortion, via the filter, wherein the isolated at least one harmonic is substantially proportional to the at least one component caused by non-linear intermodulation distortion;
• determining a measurement of at least one parameter of the isolated at least one harmonic, via a measuring device that is coupled to the filter;
• and
• modifying the signal from the determined measurement to facilitate a modification of the at least one component caused by non-linear intermodulation distortion, via a controller coupled to the measuring device.
