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