Abstract

A method of communicating over a wideband communication channel divided into a plurality of sub-channels comprises dividing a single serial message intended for one of the plurality of communication devices into a plurality of parallel messages (2904), encoding (2906) each of the plurality of parallel messages onto at least some of the plurality of sub-channels, and transmitting (2908) the encoded plurality of parallel messages to the communication device over the wideband communication channel.
