Abstract
A system may comprise a symbol mapper circuit that outputs C' quadrature amplitude modulation (QAM) symbols per orthogonal frequency division multiplexing (OFDM) symbol. The system may also comprise circuitry operable to process said C′ QAM symbols using a circulant matrix to generate a particular OFDM symbol consisting of C+Δ subcarriers, where C′ is a first integer, C is a second integer less than C′, and Δ is an integer equal to the number of non-data-carrying subcarriers in the particular OFDM symbol. The circulant matrix may be a P×P matrix, where P is an integer less than C′. The system may comprise a nonlinear circuit that introduces nonlinear distortion to said particular OFDM symbol.
