摘要

广义频分复用(GFDM)作为5G 的备选波形，具有很多OFDM 所没有的优点，但是依然具有较高的峰值平均功率比(PAPR)。从不同滤波器的相频特性不同入手，提出了一种新的降低GFDM 系统PAPR 的算法(RAF-GFDM)。该方法根据GFDM系统可以灵活选择滤波器结构的特点，通过对每路子载波随机分配不同的滤波器，调整信号叠加时的相位一致性，且不引起信号的畸变，从而有效抑制PAPR。理论分析和仿真结果证实，提出的算法在降低PAPR时没有增加额外的计算成本，且对误比特率(BER)几乎没有影响，因此具有更高的实际应用价值。

Abstract

As an alternative of the fifth generation mobile communication system waveforms

generalized frequency division multiplexing(GFDM)which has more advantages over OFDM has been trusted into the limelight.Nevertheless

GFDM still suffers from a high peak to average power ratio(PAPR).Considering that different filters have their own phase-frequency characteristics

a new algorithm based on randomly assigning filters to reduce PAPR in GFDM(RAF-GFDM)was proposed.According to the feature of GFDM system that the filter structure could be selected flexibly

different filters were assigned to subcarriers randomly to adjust the phase congruency due to signals superimposition.Additionally

this method can suppress PAPR effectively without causing signal distortion.Theoretical analysis and simulation results demonstrate that the proposed algorithm does not bring additional calculation costs while reducing PAPR and almost has no effect on the bit error rate(BER)

and it may provide a higher application value.
