Efficient PAPR Reduction in OFDM Systems using PTS-TR and GWO Optimization

Problem Definition

The issue of reducing Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems is crucial for ensuring efficient and reliable communication. While various approaches have been developed to address this challenge, the Hybrid scheme stands out as the most effective solution in terms of performance improvement. Despite its superior performance in reducing PAPR, the implementation of the Hybrid scheme is complex and can significantly impact the speed of the system operation. The complexity and reduced speed associated with implementing the Hybrid scheme highlight key limitations and pain points within the domain of PAPR reduction in OFDM systems. These challenges not only hinder the widespread adoption of the Hybrid scheme but also limit the overall efficiency and effectiveness of OFDM communication systems.

Thus, addressing these issues through research and development efforts is essential to optimize system performance and enhance the reliability of communication networks.

Objective

The objective of the study is to propose a novel approach for reducing Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems by combining the PTS-TR approach with the GWO optimization approach. This new method aims to address the limitations of existing techniques by generating sequence sets using PTS-TR and optimizing them with GWO to achieve the desired reduction in PAPR levels. By integrating these approaches, the study seeks to improve the efficiency and effectiveness of PAPR reduction in OFDM systems, ultimately enhancing the overall performance and reliability of communication networks.

Proposed Work

Since the traditional approaches for reducing PAPR in OFDM systems are quite complex and slow, this study aims to propose a novel approach that combines the PTS-TR approach with the GWO optimization approach. By utilizing these techniques, the study seeks to develop all possible sequence sets using the PTS-TR approach and then optimize these sequences using GWO to achieve the desired reduction in PAPR levels. The optimized sequences will then undergo tone reservation before being transmitted to the destination. This approach is expected to address the limitations of existing methods and improve the overall performance of PAPR reduction in OFDM systems. By leveraging the strengths of both techniques, the proposed work aims to provide a more efficient and effective solution for reducing PAPR in OFDM systems.

Through the integration of the PTS-TR and GWO optimization approaches, this study seeks to overcome the challenges associated with high complexity and slow speed in existing PAPR reduction methods. By employing the PTS-TR approach to generate sequence sets and the GWO optimization approach to optimize these sequences, the proposed work aims to streamline the process of reducing PAPR levels in OFDM systems. The utilization of GWO for sequence optimization ensures that the best possible sequence set is selected for transmission, thereby enhancing the overall efficiency and performance of the system. By adopting this novel approach, this study aims to contribute to the advancement of PAPR reduction techniques in OFDM systems and improve the overall quality and reliability of wireless communication systems.
