In the modern age, wireless communication has taken on a wide range of applications in different aspects of a human life. Ever increasing demand for higher data rates led the interest of research in FBMC (Filter Bank Multi-Carrier) as a new transmission system for the next-generation mobile communication system. FBMC is a multicarrier technique which utilized filters at the transmitting and the receiving side of the system. It is considered as one of the most promising waveform for fifth generation mobile communication system (5G). But, high value of Peak Average Power Ratio (PAPR) is considered to be one of the giant problems in FBMC. The PAPR reduction techniques used in OFDM cannot be utilized in FBMC due to its overlapping structure. Hence, new PAPR reduction techniques for FBMC have diverted the attention of researchers. In this work, dispersive selective mapping (DSLM) PAPR reduction technique is proposed. Further, the proposed technique is compared to selected mapping (SLM) and clipping PAPR reduction techniques. The simulation results show that the proposed DSLM technique gives the better performance in terms of bit error rate (BER), PAPR and complexity as compared to the SLM and clipping PAPR reduction techniques.

FBMC系统PAPR降低的改进DSLM技术

在现代，无线通信在人类生活的各个方面都有广泛的应用。对更高数据速率不断增长的需求引发了对 FBMC（滤波器组多载波）作为下一代移动通信系统的新传输系统的研究的兴趣。FBMC 是一种多载波技术，它在系统的发送端和接收端使用滤波器。它被认为是第五代移动通信系统（5G）最有前途的波形之一。但是，峰值平均功率比 (PAPR) 的高值被认为是 FBMC 中的巨大问题之一。由于其重叠结构，OFDM 中使用的 PAPR 降低技术不能用于 FBMC。因此，用于 FBMC 的新 PAPR 降低技术转移了研究人员的注意力。在这项工作中，提出了色散选择性映射 (DSLM) PAPR 降低技术。此外，将所提出的技术与选择映射 (SLM) 和限幅 PAPR 降低技术进行比较。仿真结果表明，与 SLM 和限幅 PAPR 降低技术相比，所提出的 DSLM 技术在误码率 (BER)、PAPR 和复杂性方面具有更好的性能。
