Resource Overview
The tone reservation technique reduces the peak-to-average power ratio (PAPR) in OFDM signals by using a clipping-based method to identify and eliminate peak signals through reserved subcarriers.
Detailed Documentation
This document presents a tone reservation method designed to reduce the peak-to-average power ratio (PAPR) in OFDM signals. The technique employs a clipping algorithm to detect and cancel signal peaks by utilizing reserved subcarriers that carry no data. This approach effectively minimizes PAPR while maintaining signal integrity, thereby improving overall transmission quality and system stability. The implementation typically involves identifying peak magnitudes exceeding a predefined threshold and generating cancellation signals using optimized reserved tones.
