Abstract
A system includes a modulator to modulate data using Quadrature Phase Shift Keying modulation and dual sub-carrier modulation to generate modulated symbols for transmission on a plurality of subcarriers. A repetition module repeats the modulated symbols from a first half of the plurality of subcarriers to a second half of the plurality of subcarriers. A phase rotation module rotates phase of the modulated symbols on selected subcarriers of the second half of the plurality of subcarriers. The selected subcarriers include all of the second half of the plurality of subcarriers. The phase rotation module rotates the phase of the modulated symbols on all of the second half of the plurality of subcarriers to conjugate the modulated symbols on all of the second half of the plurality of subcarriers relative to corresponding modulated symbols on all of the first half of the plurality of subcarriers.
