Detailed Documentation
This paper presents a peak-to-average power ratio (PAPR) reduction technique for OFDM systems using predistortion. Through MATLAB simulations, we compared constellation diagrams with and without the predistortion technique, revealing noticeable performance differences. The implementation involves generating OFDM signals with QAM mapping, applying a predistortion algorithm before transmission, and analyzing the resulting signal quality. The simulation code includes key functions for signal modulation, predistortion processing, and constellation plot generation to demonstrate the effectiveness of the technique in reducing PAPR while maintaining signal integrity.
