ABSTRACT:
The aim of the invention is to detect the remaining carrier power on a multi-carrier signal that is QAM-modulated in the 8K mode according to the DVB-T-standard. Said signal is provided with a central carrier which is situated in the center of the individual carriers and, at times, is a continual and, at times, a scattered pilot. The influence of the remaining carrier power on a carrier that is adjacent to the central carrier is detected and then converted to the central carrier.
