摘要： A system linearization assembly generally includes a filter that is coupled to a measuring device. The filter is configured to receive 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, such as an odd-order intermodulation distortion component. The filter is also configured to isolate at least one harmonic of the frequency components with the same order as the component caused by non-linear intermodulation distortion. The measuring device is configured to measure at least one parameter of the isolated harmonic. The system linearization assembly also includes a controller coupled to the measuring device. The controller is configured to modify, for example by minimizing, the signal from the determined measurement to facilitate a modification, such as a reduction, of the component caused by non-linear intermodulation distortion.

摘要： A system linearization assembly generally includes a delay device that receives an input signal from a signal source and delays the input signal by a predetermined delay function. An attenuation device receives a modified output signal from a signal modifying device, wherein the output signal is based on the input signal and includes a time varying parameter representing a plurality of frequency components including at least one component caused by non-linear intermodulation distortion. The attenuation device attenuates the output signal by a factor that is equal to at least one parameter of the modifying device. A computing device compares the attenuated output signal with the delayed input signal to obtain a resultant signal that includes the component caused by non-linear intermodulation distortion. A detection device detects at least one parameter of the resultant signal. Based on the detected parameter, a controller facilitates a modification of the component.
