APPARATUS AND METHOD FOR COMPENSATING PHASE DISTORTION

摘要

PURPOSE: An apparatus and method for compensating phase distortion are provided to compensate phase distortion generated in a power amplified output signal. CONSTITUTION: An amplifier has an input connected to a phase synchronization and an output of upper transformation loop(30-39). The loop has a first and a second feedback loops(33, 36). The first feedback loop(33) is connected to a tap means(37) tapping off one part of a modulated signal. The second feedback loop(36) is connected to a tap means(38) tapping off the power amplified modulation signal. The feedback loops(33, 36) are connected to two inputs of a composition means(35) compositing a two input signals provided from the feedback loops(33, 36).
