Abstract
A system includes a modulator, a repetition module, and a phase rotation module. The modulator is configured to (i) modulate data using a first modulation scheme and dual sub-carrier modulation, and (ii) generate modulated symbols for transmission on a plurality of subcarriers. The dual sub-carrier modulation modulates the same information on a pair of subcarriers. The repetition module is configured to repeat the modulated symbols from a first half of the plurality of subcarriers to a second half of the plurality of subcarriers. The phase rotation module is configured to rotate phase of the modulated symbols on selected subcarriers of the second half of the plurality of subcarriers. The selected subcarriers of the second half of the plurality of subcarriers include at least one half of the second half of the plurality of subcarriers.
