Abstract
A method for determining notching parameters for a PLC (Power Line Communication) Signal in a PLC system, where, by notching in a targeted fashion, frequency ranges are omitted in the PLC signal and the notching parameters are selected such that any interference of the PLC signal with a radio signal is largely avoided, is characterized with regards to the determination of notching parameters even during operation of the PLC system such that, at least for a section of the PLC signals, a signal-interference ratio (SIR) is formed which, depending on the SIR, assesses the signal strength of a radio signal and, based on the assessment notching parameters, are determined or adjusted. A respective PLC system is provided.

A method to determine one or more notching parameters for a PLC (Powerline Communication) signal in a PLC system, where, by way of notching, frequency ranges in the PLC signal are omitted in a targeted fashion and the notching parameters are selected, such that any interference of the PLC signal with a radio signal is largely avoided, wherein:
- at least for one range of the PLC signal, a signal-to-interference ratio (SIR) is formed;
- dependent on the formed SIR, a signal strength of a radio signal is assessed;
- and
- based on the assessment, one or more notching parameters are determined or adjusted.
