Initial code acquisition in the cooperative Non-Coherent MIMO DS-CDMA downlink
, 2009 In this paper we investigate a realistic code acquisition assisted cooperative Non-Coherent (NC) Multiple-Input Multiple-Output (MIMO) DS-CDMA downlink scenario, when communicating over uncorrelated single-path and multi-path Rayleigh channels.

Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements
Advanced Optical Materials, EarlyView.This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Synchronisation Issues in Non-coherent MIMO Systems
In this article, we identify some of the key problems that may be encountered when designing Non-Coherent (NC) Multiple-Input Multiple-Output (MIMO) DownLink (DL) synchronisation schemes for communicating over multi-path fading channels.

LLM‐Integrated Human–Robot Interaction System for Microrobots
Advanced Robotics Research, EarlyView.This paper proposes an LLM‐based control framework for guiding microrobots using human natural language. This framework can convert the natural human speech into safe and executable command sets for reliable navigation in complex environments. The experimental results show high accuracy and robustness in task performance, demonstrating the potential of
