PAPR reduction with mixed-numerology OFDM [PDF]
IEEE Wireless Communications Letters, 2019 High peak-to-average power ratio (PAPR) is a critical problem in orthogonal frequency-division multiplexing (OFDM). The fifth-generation New Radio (5G NR) facilitates the utilization of multiple heterogeneous bandwidth parts (BWPs), which complicates the

PAPR Reduction Scheme for OFDM
Procedia Technology, 2012 This paper focused on peak to average power ratio (PAPR) reduction scheme for OFDM system. OFDM has several properties which make it an attractive modulation scheme for high speed transmission. the main draw back of OFDM is high PAPR.

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.
