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.

Fractional Fourier Domain PAPR Reduction

GLOBECOM 2025 - 2025 IEEE Global Communications Conference
High peak-to-average power ratio (PAPR) has long posed a challenge for multi-carrier systems, impacting amplifier efficiency and overall system performance. This paper introduces dynamic angle fractional Fourier division multiplexing (DA-FrFDM), an innovative multi-carrier system that effectively reduces PAPR for both QAM and Gaussian signals with ...
