Abstract

A construction scheme of M-QAM (quaternary amplitude modulation) signals using quaternary phase-shift keying (QPSK) constellations for the orthogonal frequency division multiplexing (OFDM) has been proposed, when M= 2k and k is an even number. In this paper, we extend Rudin-Shapiro polynomials (RSP) to the generalized Rudin-Shapiro polynomials (GRSP). Based on the generalized Rudin-Shapiro polynomials (GRSP), upper bound of peak-to-mean envelope power ratio (PMEPR), code rate, the minimum Hamming distance for the M-QAM sequences are derived.
