Abstract: The invention relates to a method and an apparatus for distortion compensation of signals transmitted via a bidirectional link between a client device and a host device, said method comprising the steps of performing a post-distortion-compensation for an upstream signal received by the host device on said bidirectional link by adjusting post-compensation parameters of a post-compensation unit of said host device and transforming the adjusted post-compensation parameters into pre-compensation parameters of a pre-compensation unit of said host device which performs a pre-distortion compensation for a downstream signal transmitted by said host device via said bidirectional link to said client device.
