摘要

Filter Bank Multicarrier (FBMC) is an attractive modulation scheme for advanced wireless communication systems due to its capability to address issues like spectral efficiency and interference resilience. However, FBMC, like other multi-carrier modulation techniques, suffers from a high Peak-to-Average Power Ratio (PAPR), limiting its practical deployment. This research focuses on mitigating PAPR in FBMC through the application of the Partial Transmit Sequence (PTS) method. The Partial Transmit Sequence technique, widely used in filter bank multi-carrier (FBMC) systems, has shown effectiveness in reducing PAPR by optimizing the phase factors of sub-blocks. Extending this methodology to FBMC requires a nuanced understanding of the unique characteristics of FBMC signals. The distinctive filter bank structure in FBMC introduces challenges and opportunities for PAPR reduction, making it a compelling area for investigation. The proposed research aims to explore and optimize the PTS method for FBMC, considering the filter bank characteristics and the peculiarities of FBMC signals. The study involves developing novel algorithms for selecting and applying phase factors to sub-blocks, tailored to the FBMC framework. Additionally, the research investigates the trade-off between PAPR reduction and the computational complexity associated with PTS in the FBMC context. This work leverages simulations and analytical modeling to assess the performance gains achieved by the PTS method in reducing PAPR for FBMC systems. Through systematic experimentation, the research aims to identify optimal configurations, offering insights into the parameters that most significantly impact PAPR reduction in FBMC using PTS. The outcomes of this study are expected to contribute to the design and optimization of FBMC-based communication systems, fostering advancements in wireless communication technologies. By addressing the PAPR challenges inherent in FBMC, the research aims to enhance the reliability and efficiency of FBMC for practical deployment in emerging communication standards and applications. The simulation of an FBMC PTS reduction method is presented in this work. The results of the simulation show that the suggested strategy outperforms the traditional PAPR reduction strategy.
