Abstract :
In this paper, we propose a method to reduce the PAPR in OFDM by combining the PTS with Golay complementary sequences and Reed-Muller codes. The original signal is divided into several disjoint subblocks, one subblock for pilots and the other subblocks of Golay complementary sequences generated from particular cosets of the Reed-Muller code for information and phase rotation factors of PTS. The optimal combination of phase rotation factors is obtained as minimizing the PAPR of an OFDM symbol. The simulation results, CCDF of PAPR and BER through Rayleigh fading channel, illustrate the effectiveness of the proposed method
