Joint space-time trellis code detection and MIMO equalisation via particle filtering [PDF]

, 2004
In this contribution we address the problem of MIMO equalisation and transmit diversity. More specifically, we develop a method that jointly decodes space time trellis coded modulation (STTCM) encoded signals and equalises the MIMO channels.

The genetic basis of microbiome recruitment in grapevine and its association with fermentative and pathogenic taxa

New Phytologist, Volume 248, Issue 1, Page 178-192, October 2025.
Summary While grapevine is an exceptional perennial model for studying host‐microbiome interactions, the host genome's role in microbiome assembly is often masked by environmental factors. This research provides a first insight into the genetic mechanisms shaping berry‐associated microbial communities.

Two‐Way Relaying for Orbital Angular Momentum LOS Transmission

International Journal of Communication Systems, Volume 38, Issue 13, 10 September 2025.
This paper investigates two‐way relaying (TWR) for orbital angular momentum (OAM)‐based line‐of‐sight (LOS) transmission. Low‐complexity near‐ML detectors are proposed for OAM mode division multiplexing and index modulation. Theoretical analysis and simulations confirm that TWR significantly improves bit error performance and spectral efficiency over ...

A path splitting and pruning strategy on list decoder for PAC codes

IET Communications, Volume 18, Issue 18, Page 1292-1299, November 2024.
The paper introduces a novel low‐complexity list decoding algorithm for polarization‐adjusted convolutional codes. By incorporating path splitting and pruning strategies based on highly reliable information bits, our algorithm significantly reduces decoding complexity while maintaining optimal performance.
