Post-amplifier filter rejection equalization










Image Number 2 for United States Patent #6674808.

A post-HPA filter rejection equalizer system and method locally equalizes post-HPA filtering. A predistorter (20) uses a phase error to control the predistortion, and an equalizer (46) uses a magnitude error to control the equalization. The equalizer samples the HPA output multiple occurrences in a burst fashion. The equalized signal is then used to determine phase and magnitude errors. The phase errors (54) are used to update the predistorter (20), and the magnitude errors (52) are used to update the analytic equalizer.
