A method for transmitting data in a communication system employing an encoding scheme includes processing data in accordance with a particular processing scheme to provide a plurality of information symbols; shaping a constellation of the plurality of information symbols to obtain a plurality of shaped symbols; processing the plurality of shaped symbols in accordance with the encoding scheme to obtain a plurality of transformed signals such that the peak to average power ratio (PAR) of the plurality of transformed symbols is lower than the PAR would be if the information symbols were not shaped into shaped symbols prior to processing into transformed symbols, wherein the encoding scheme may be expressed in a form x=Gs, sepsilonZN, GepsilonRNxN, where x is an isomorphic vector representation of transformed signals, G is an NxN invertible generator matrix, s is a vector of a plurality of information symbols, and R represents the real domain; and transmitting the plurality of transformed signals over a communication network. |
