Echo compensation device in signal transmission has non linear compensating branches with non linear function between linear filters

摘要

An echo compensation device in signal transmission comprises non-linear compensations and a correction unit to combine the incoming and compensated signals. The non-linear compensation comprises parallel branches (20) with a non-linear function unit (22) between two linear filters (21,23) and a unit (16) to combine the branches. An independent claim is also included for a device as above having a different arrangement of the non-linear function unit and filters.
