摘要

由于需求的数量可能每年都在增加，因此世界需要转向先进的技术蜂窝系统。研究人员提出的滤波OFDMA (F- OFDMA)是为5G系统提出的新波形。但是高峰值平均功率比(PAPR)仍然是该系统的缺点。本文采用双分组编码对F-OFDMA中PAPR的性能进行了评价。本文提出了霍夫曼编码和Turbo编码两种仿真方法。仿真结果表明，在64 APSK调制下，所提出的Huffman编码方案使F-OFDMA系统的PAPR降低了17.17%，而Turbo码方案仅降低了13.13%。

Reduction of PAPR using Huffman Coding and APSK Modulation Technique for F-OFDMA in 5G System

As the number of demand may increase per year, thus the world need to move to the advance technologies cellular system. Researcher come up with Filtered-OFDMA (F- OFDMA) is the new waveform that has been proposed for 5G system. But still high Peak to Average Power Ratio (PAPR) is the drawbacks of the system. This paper evaluates the performance of PAPR in F-OFDMA by using two block coding. Huffman coding and Turbo codes are the proposed method for this simulation. From the analysis, the simulation results showed that proposed method Huffman Coding scheme greatly reduce the PAPR in F-OFDMA system by 17.17% in 64 APSK modulation while Turbo code scheme is only by 13.13%.
