PAPR reduction in OFDM

PAPR reduction in OFDM is a research topic within Electrical and Electronic Engineering. Science Explorer counts 15k research works in it since 1959. 9.8% of them reached the world's top 10% most cited for their field and year.

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.
