Method and system for providing digital adaptive predistortion in a subscriber station

摘要

A method for providing digital adaptive predistortion in a subscriber station is provided that includes applying predistortion, based on a set of predistortion characteristics, to a transmit signal to generate a predistorted signal. An amplifier input signal is generated based on the predistorted signal. The amplifier input signal is amplified to generate an amplified signal. The amplified signal is sampled to generate a sampled signal. The sampled signal is processed through a receive channel of the subscriber station to generate a processed signal. A determination is made regarding whether to adjust the set of predistortion characteristics based on the processed signal.
