Research on Peak-to-Average Power Ratio Reduction for Multicarrier Signal Base on Phase Sequence
摘要
Abstract
To overcome the shortcoming of high Peak-to-Average Power Ratio(PAPR)in multicarrier signal system,combining the traditional Tone Reservation (TR)algorithm with the initial phase of the multicarrier signal,a Newman-TR method is proposed to reduce PAPR. Simulation shows that the Newman-TR method algorithm can achieve good PAPR reduction and bit errror rate is not increased in the process. However,it has a high computational cost. Aimiling at this problem,a local optimal search method which is instead of the global optimal search is proposed in this paper. The new method can reduce the computational complexity much more effectively and improve the practical feasibility of the improved algorithm.关键词
