摘要

A new phasing scheme to achieve the lowest peak-toaverage power ratio (PAPR) of OFDM system is presented in this paper, which is based on a global optimization combination of the initial phases using particle swarm optimization (PSO). The particle swarm optimization is applied to search the optimal combination of phase factors, which can achieve the OFDM signals with low PAPR and reduce the computational complexity significantly. To validate the analytical results, some simulations have been conducted, showing that the proposed schemes can achieve the lowest PAPR with low computational complexity.
