Abstract
We present a quadrature phase-shift keying (QPSK) coding scheme for multicarrier communications. The scheme supports simple encoding and extremely simple maximum-likelihood (ML) decoding algorithms for orthogonal frequency-division multiplexing (OFDM). Moreover, all the codewords have peak-to-mean envelope power ratio (PMEPR) of at most 6 dB
