A communications system (100) includes a segmenter (204) for dividing a plurality of bits into a first segment and a second segment and a symbol mapper (208) for generating a plurality of symbols based on the first segment. The system also includes a co-set selector (214) for selecting a plurality of co-set waveforms from a plurality of orthogonal waveforms based on a co-set address defined by the second segment, a number (K) of the plurality of co-set waveforms being less than a number (N) of the plurality of orthogonal waveforms. The system further includes a modulator (210) for modulating the plurality of symbols based on the plurality of co-set waveforms.
