Abstract: OFDM is a powerful multicarrier transmission technique used extensively for wireless applications. High PAPR is one of the deleterious problems of OFDM. This paper reviews basic OFDM system and PAPR problem associated with it. Also, the construction of M-QAM particularly 16-QAM sequences using QPSK Golay sequences over 4ο‚’ is conferred. It is elucidated that a 16-QAM constellation can be written as the vector sum of two QPSK constellations respectively. The Golay complementary sequences over 4ο‚’ are then used to construct 16-QAM OFDM sequences with low PAPR. The PAPR bound for the generated 16-QAM sequences is calculated to be 5.56dB.

Keywords: OFDM, PAPR, M-QAM, QPSK, Golay Complementary Sequences.
