A method comprising mapping data onto odd frequency subcarriers of a plurality of non-overlapping frequency subcarriers, wherein each of the non-overlapping frequency subcarriers comprises a center frequency that is an odd integer multiple of a lowest center frequency, producing a time signal based on the mapping, applying soft clipping (SC) to signal amplitudes of the time signal according to a polynomial function, and producing a positive-amplitude signal based on the applying.
