The cause of high PAPR in IEEE 802.16d OFDM system is investigated. Based on the existed PTS and companding algorithms to reduce the PAPR, the best combined rules in algorithms are studied. The performances of combined algorithms (PTS-Companding) are analysed. Simulation results show that PTS-Companding is the better combined algorithm. It can reduce the PAPR efficiently, and has lower computational complexity and restrain noise as well.
