Abstract

A multi-tone modulation method is provided wich reduced a peak average power ratio. The method involves defining a respective signal constellation for each center frequencies having redundant mappings for each set of input elements, and then selecting a particular permutation of mappings having a reduced peak power for the multi-tone signal. A method of shaping is also employed in wich a hierarchy of blocks are defined, each layer having fewer blocks than each previous layer. The hierarchy is used to select a particular subset of an expanded constellation.
