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

open access: yes, 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

open access: yesNew 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

open access: yesInternational 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 ...
