A method for transmitting signals over a power line network, wherein within the power line network at least one transmitter and at least one receiver communicate via at least two channels, each of the channels having a respective feeding port of the at least one transmitter and a respective receiving port of the at least one transmitter, and the transmitter includes at least two feeding ports, the method comprising:
- determining a channel characteristic of each of the channels;
- applying a feeding port selection criterion based on the channel characteristic;
- and
- selecting an excluded feeding port among the at least two feeding ports based on the feeding port selection criterion, wherein the excluded feeding port is not used during further communication.
