1. A method for use with a communication system including a plurality of subcarrier signal paths, a common signal path and a communications channel having a communications channel group signal delay, the method comprising the steps of:

  • operating a processing device to calculate a subcarrier signal path group signal delay introduced by a first one of the subcarrier signal paths;

    operating said processing device to calculate a common signal path group signal delay introduced by the common signal path;

    generating, as a function of the calculated subcarrier signal path group signal delay, calculated common signal path group signal delay, and communications channel group signal delay, a minimum cyclic prefix duration.
