Abstract

A method of operating in a network (e.g., a power line communication network) in which a plurality of stations communicate over a shared medium (e.g., an AC power line) having a periodically varying channel. The method includes determining a plurality of channel adaptations (e.g., tone maps) for communication between a pair of stations, and assigning a different one of the plurality of channel adaptations to each of a plurality of phase regions of the periodically varying channel.
