Peak-to-average power ratio of good codes for Gaussian channel [PDF]
, 2014 Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

A joint OFDM PAPR reduction and data decoding scheme with no SI estimation [PDF]
, 2016 The need for side information (SI) estimation poses a major challenge when selected mapping (SLM) is implemented to reduce peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems.

Business Strategy and the Environment, EarlyView.ABSTRACT Focusing on firm‐size heterogeneity, this study examines how institutional reform reshapes the effects of environmental, social, and governance (ESG) disclosure on firm value. Using 2019–2023 panel data on 1427 Japanese listed firms (before and after the 2022 Tokyo Stock Exchange reorganization and Corporate Governance Code revision), this ...

An Enhanced Companding Algorithm for Universal Filtered Multi-Carrier System
ETRI JournalThis paper proposes a new companding scheme called three μ-law compand-ing to reduce the peak-to-average power ratio (PAPR) in a universal filtered multicarrier system. The proposed scheme is more flexible and provides better PAPR reduction and bit error

Modified DRM+ signal generation algorithm with reduced crest factor
Физика волновых процессов и радиотехнические системы, 2020 To reduce the crest factor in the DRM+ system due to the limitations imposed by the standard the peak limiting method (clipping) and the window weighting method, which are based on signal distortion, are widely used.

Walsh‐Hadamard‐transform‐based SC‐FDMA system using WARP hardware
ETRI Journal, 2021 Single‐carrier frequency division multiple access (SC‐FDMA) is currently being used in long‐term evolution uplink communications owing to its low peak‐to‐average power ratio (PAPR). This study proposes a new transceiver design for an SC‐FDMA system based
