An intelligent genetic algorithm for PAPR reduction in a multi-carrier CDMA wireless system
, 2008 — A novel intelligent genetic algorithm (GA), called Minimum Distance guided GA (MDGA) is proposed for peak-average-power ratio (PAPR) reduction based on partial transmit sequence (PTS) scheme in a synchronous Multi-Carrier Code Division Multiple Access (

Spreading Code Design for a MC-CDMA Based GNSS Pilot Signal
, 2010 MC-CDMA can represent an alternative to classical DS-CDMA for the design of GNSS ranging signals. A first requirement MC-CDMA signals must fulfill is that their generation on a satellite payload be feasible.

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

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

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The heterobimetallic amino‐acid dithiocarbamates [M(H2O)n]2[Pt(L)2] (M = Ca, Sr, Ba, Zn, Cd; L = N‐dithioato‐iminodiacetate) are thermally dehydrated to their respective anhydrates M2[Pt(L)2], which further yield metal sulfate or oxide particles decorated with finely distributed metallic platinum upon combustion in air. The thermal decomposition of the
