IET Communications, Volume 20, Issue 1, January/December 2026.This work extends the Polyanskiy‐Poor‐Verdu (PPV) framework to lognormal wireless links. Specifically, the paper derives a closed‐form approximation for the average error probability under lognormal distribution, effectively generalizing the PPV analysis beyond the additive white Gaussian noise assumption.

Low-PAPR Joint Channel Estimation and Data Detection in ZP-OTFS System
, 2023 Orthogonal Time Frequency Space (OTFS) systems face significant challenges in channel estimation due to high pilot overhead and peak-to-average power ratio (PAPR). To address these issues, we propose a two-step channel estimation method for Zero-Pad OTFS

An ML-assisted OTFS vs. OFDM adaptable modem
, 2023 The Orthogonal-Time-Frequency-Space (OTFS) signaling is known to be resilient to doubly-dispersive channels, which impacts high mobility scenarios. On the other hand, the Orthogonal-Frequency-Division-Multiplexing (OFDM) waveforms enjoy the benefits of ...

Expanding the Chemical Space of Sugar Frameworks by Quaternization of the Anomeric Carbon Atom
European Journal of Organic Chemistry, Volume 28, Issue 37, October 11, 2025.Novel C,C and C,N bifunctional fucosides are stereoselectively obtained starting from a common anomeric bromide intermediate. The developed methodology expands the chemical space at the anomeric position of fucose and supports future applications in glycomimetics design.
