        abstract = {Orthogonal Frequency Division Multiplexing (OFDM) is widely recognized as an efficient multicarrier transmission technique for high-speed wireless communication. However, its inherent high Peak-to-Average Power Ratio (PAPR) remains a major limitation, leading to inefficient power amplifier operation and signal distortion. This paper provides a comprehensive review of prominent PAPR reduction techniques, including clipping and filtering, coding, tone reservation and injection, Selected Mapping (SLM), Partial Transmit Sequence (PTS), and advanced methods such as lattice-based and precoding schemes for MIMO-OFDM systems. Trade-offs in terms of Bit Error Rate (BER), spectral efficiency, computational complexity, and system compatibility are discussed. Simulation results highlight the effectiveness of these techniques in reducing PAPR while addressing practical implementation challenges. Future directions focus on low-complexity, standard-compliant solutions suitable for next-generation wireless networks.},
