Abstract

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 channel including a respective feeding port of at least one transmitter and the respective receiving port of the at least one transmitter and transmitter including at least two feeding ports. The method: determines a channel characteristic of each of the channels; applies a feeding port selection criterion based on the channel characteristic; and selects 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. A corresponding power line communication modem can implement the method.
