Abstract :
We present a QPSK coding scheme for use in multicarrier communications. The scheme supports simple encoding and extremely simple maximum likelihood (ML) decoding algorithms for orthogonal frequency division multiplexing (OFDM) applications. Moreover, all the codewords have a peak-to-mean envelope power ratio (PMEPR) of at most 4
