摘要: A digital predistorter for improving the performance of a narrow passband filter near the output is disclosed. The digital predistorter provides amplitude correction to the signal based on the characteristics of the passband filter. A filter group delay predistorter may also be employed to correct group delay variation introduced by the narrow passband filter.
