Abstract
High peak-to-mean envelope power ratio has been a major issue in the implementation of orthogonal frequency division multiplexing systems in low cost application devices. In this letter, we construct code with low peak to mean envelope power ratio based on construction of STAR-16-QAM constellation as a scaled set sum of two QPSK constellations. The construction of Golay sequences based on STAR-16-QAM constellation is shown and upper bound for peak-to-mean envelope power ratio for OFDM is derived.
