Abstract: This paper interprets the reduction of peak-to-average power ratio (PAPR) of 64-quadrature amplitude modulation (QAM) signals in the most promising technique of high speed parallel data transmission, well-known as orthogonal frequency division multiplexing (OFDM). As one of the major impediments to deploying OFDM is the high PAPR of the uncoded OFDM signals, so the Golay complementary sequences are used to construct 64-QAM OFDM sequences to provide low PAPR. It has been explicated that a 64-QAM constellation can be written as the vector sum of three QPSK constellations respectively. Further it has been investigated that by using these sequences, PAPR is bounded above by6.69dB.
