OFDM PAPR Reduction Using PTS Technique

Resource Overview

OFDM PAPR reduction with PTS technique (source code implementation for three segmentation methods)

Detailed Documentation

In OFDM systems, PAPR (Peak-to-Average Power Ratio) represents a significant challenge as it can lead to nonlinear distortion and degrade system performance. To address this issue, the Partial Transmit Sequence (PTS) technique is widely employed. PTS is a method that divides the original OFDM signal into multiple sub-signals and modulates them separately. This approach effectively reduces the overall PAPR value, thereby enhancing system performance. The PTS technique features three commonly used segmentation methods: segment-based PTS, subcarrier-based PTS, and interleaved PTS. The implementation typically involves dividing input data into partitions, applying phase rotation factors, and selecting optimal combinations through PAPR calculation algorithms. For practical implementation of these methods, you can refer to the following source code examples.
