The Filter Bank Multicarrier (FBMC), one of the multi-carrier modulation technique are subjected to extreme intensities of Peak to Average Power Ratio (PAPR). Moreover, the FBMC is a firm user, like the waveform-centred framework in the unconventional wireless communication frameworks, such as the 5G telecommunication system. This system framework acts as an alternative to the Orthogonal Frequencies Divisions Multiplexing (OFDM), including the Discrete Fourier Transforms (DFT). Signal Spreading is applicable in the FBMC purposed for PAPR reductions, which exemplifies a significant computational increase in its complexities that does not necessitate an overhead of signal placed at the receiver end. In this proposed work recommends the application of the general DFT, which is considered as a substitute to the DFT-spreading purposed for the PAPR reductions. To further we have derived the conditions whereby the Generalized Discrete Fourier Transform (GDFT) can significantly apply the single carriers influenced of the DFT-spreading, which targets the reductions in the PAPR. Moreover, this paper proposes a developed algorithm centred on the GDFT that considers more PAPR reductions eliminating any further computational complexities. Therefore, the recommended algorithm has been formulated to utilized Side Information (SI) represents a single bit of every data segment. This developed algorithm is also applicable in more enhanced DFT-spreading frameworks aimed at comparing data. Based on the collected simulation findings, it is evident that varied number of sub-carriers GDFT-spreading, which considers the availability or the presence of the developed algorithm, indicates the recommendable framework signifying that the enhanced algorithms received in most instances is an additional PAPR amount reductions based on other DFT-spreading frameworks. These frameworks, including the developed GDFT indicate effective power spectral densities (PSD) compared to varied DFT-spreading frameworks.

缩回本文：基于滤波器组多载波的广义离散傅里叶变换，可降低峰均功率比

多载波调制技术之一的滤波器组多载波（FBMC）受到峰均功率比（PAPR）的极端强度影响。此外，FBMC是坚定的用户，就像非常规无线通信框架（如5G电信系统）中的以波形为中心的框架一样。该系统框架可替代正交频分复用（OFDM），包括离散傅立叶变换（DFT）。信号扩展适用于旨在降低PAPR的FBMC，这说明其复杂度的显着计算增加，而不必增加接收端的信号开销。在这项拟议工作中，建议使用通用DFT，它被认为是用于降低PAPR的DFT扩展的替代方案。更进一步，我们得出了条件，广义离散傅里叶变换（GDFT）可以显着应用受DFT扩展影响的单个载波，其目标是降低PAPR。此外，本文提出了一种以GDFT为中心的开发算法，该算法考虑了更多的PAPR降低，从而消除了进一步的计算复杂性。因此，推荐算法已被公式化为利用辅助信息（SI）表示每个数据段的单个位。此开发的算法还适用于旨在比较数据的更增强的DFT扩展框架。根据收集到的仿真结果，很明显，分布了不同数量的子载波GDFT，考虑到已开发算法的可用性或是否存在，表示可推荐的框架，表示在大多数情况下接收到的增强算法是基于其他DFT扩展框架的额外PAPR数量减少。与各种DFT扩展框架相比，这些框架（包括已开发的GDFT）表明有效功率谱密度（PSD）。
