Optimization of Tone Reservation-Based PAPR Reduction for OFDM Systems [PDF]
Radioengineering, 2017 A major drawback of orthogonal frequency division multiplexing (OFDM) is its high peak-to-average power ratio (PAPR). Tone reservation (TR) is one of the numerous methods for reducing the PAPR.

A Novel Approach to Deducing of the Data- PAPR Relation for OFDM System
Journal of Engineering and Sustainable Development, 2012 Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high-data-rate transmission in wireless and wired applications. The main drawback of the OFDM technique is its high peak to average power ratio (PAPR).
