Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

PAPR Reduction and Data Security Improvement for OFDM Technique Using Chaos System
Journal of Communications Software and Systems, 2019 Orthogonal Frequency Division Multiplexing (OFDM) is the most popular multicarrier technique because it produces several advantages such as higher spectral efficiency, high transmission rate, robustness to fading channel and etc..

Symbol interferometry and companding transform for PAPR reduction of OTFS signal
ETRI JournalThis paper presents methods for reducing the peak-to-average power ratio (PAPR) of the orthogonal time frequency space (OTFS) signal. These methods mainly consist of two operations: symbol interferometry (SI) and either μ-law or A-law companding.

Universal Filtered Multi-Carrier System Based on Selective Mapping
Xibei Gongye Daxue Xuebao, 2019 Internet of things (IoT) and machine-to-machine (M2M) communication are characterized by short periods and bursts. Traditional orthogonal frequency division multiplexing (OFDM) has not meet the demand for such traffic, while IoT and M2M communication ...

Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission
, 2011 The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log$(N)$ barrier where $N$ is the number of subcarriers which has been theoretically ...

The FEBS Journal, Volume 292, Issue 21, Page 5659-5675, November 2025.Human tissue kallikrein 14 (KLK14), a skin protease, may mediate paracrine signaling in wound healing. KLK14 released by epithelial cells activates fibroblasts via PAR‐1 activation, inducing IL‐6, IL‐8, and CXCL1 expression. These cytokines in turn promote keratinocyte proliferation and migration, resulting in wound closure.

, 2016 The forthcoming 5G cellular network is expected to overlay millimeter-wave (mmW) transmissions with the incumbent micro-wave ({\mu}W) architecture. The overall mm-{\mu}W resource management should therefore harmonize with each other.

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 5, September/October 2025.ABSTRACT In this article, we provide a novel, expanded, and adapted pruning approach for the Simplified Volterra Series (SVS) model that makes it applicable to a wider range of Power Amplifiers (PAs). The proposed Modified SVS (MSVS) model is then applied in a Digital Predistortion (DPD) architecture to linearize a 25 W Gallium Nitride (GaN) RF PA.
