SYSTEM AND METHOD FOR COMPENSATING FOR CODEC DC OFFSET THROUGH A DC BLOCKING CHANNEL AND MODEM INCORPORATING THE SAME

摘要

The invention codec DC offset compensation system and method and , to a modem using such a system or method . In one embodiment , the system of the present invention , (1) DC offset to transmit by generating a DC offset indicator signal corresponding to a DC offset present along a transmission path to a receiving codec and the compensator (2) connected to the DC offset compensator and a DC offset encoder is applied to a user data symbol stream transmitted along the transmission path, the time-varying DC offset compensating signal based on it , and receives the DC offset indicator signal .
