PAPR reduction in OFDM

This cluster of papers focuses on peak-to-average power ratio (PAPR) reduction techniques for orthogonal frequency division multiplexing (OFDM) and multicarrier transmission systems. It covers various methods such as clipping, filtering, partial transmit sequences, companding, and waveform contenders for 5G networks. The cluster also explores the impact of nonlinear distortion, channel estimation, and spectral efficiency in the context of PAPR reduction.
