Orthogonal Frequency Division Multiplexing (OFDM) stands out as a widely used transmission method in today's communication systems. However, high peak to average power ratio (PAPR) is a major drawback of this modulation technique. It poses significant problems in communication systems, leading to signal distortion and reduced power efficiency. To tackle this challenge, this paper broadly classifies and investigates popular PAPR reduction techniques, providing a thorough examination of their individual effectiveness. We compare these techniques, analyzing how they perform when we increase the number of subcarriers, use cyclic prefixes, and consider the time complexity of different methods. Rather than focusing on a specific technique, this dissertation provides a broad understanding of various approaches, aiming to help in choosing the most suitable method based on specific system requirements.
