Low complexity of PTS Technique for PAPR Reduction of OFDM modulation in wireless communications fifth Generation

Abstract

The ever-increasing demand for high data rates and reliable communication in fifth-generation (5G) wireless networks has highlighted the importance of efficient modulation techniques. This thesis focuses on a low-complexity Partial Transmit Sequence (PTS) technique aimed at reducing the Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems. High PAPR in OFDM causes power inefficiency and nonlinear distortions, which degrade system performance. The proposed low-complexity approach achieves significant PAPR reduction while minimizing computational overhead, making it suitable for practical 5G implementations. Simulation results validate the effectiveness of the method, promising enhanced power efficiency and improved signal integrity in future wireless communications.
