On minimizing the peak-to-average power ratio of multi-carrier modulation signals using simulated annealing

This paper presents a new phasing scheme to achieve the lowest peak-to-average power ratio (PAPR) of multi-carrier modulation (MCM) signals than that of some existing methods. The new scheme is based on a global optimization combination of the initial phases using simulated annealing. The flexibility in different modulation formats and subcarrier sizes make the proposed scheme more suitable for reduction PAPR of MCM signals. To validate the analytical results, some simulations have been conducted, showing that the proposed schemes can achieve the lowest PAPR among the any value yet reported schemes.
