Space-Time Signal Design for Multilevel Polar Coding in Slow Fading Broadcast Channels
, 2019 Slow fading broadcast channels can model a wide range of applications in wireless networks. Due to delay requirements and the unavailability of the channel state information at the transmitter (CSIT), these channels for many applications are non-ergodic.

Energy Internet, EarlyView.ABSTRACT Accurate identification of broadband oscillation types is a prerequisite for implementing appropriate control strategies. The strongly nonlinear, nonstationary and multi‐modal characteristics of broadband oscillation signals impose higher demands on identification methods. Practical applications face challenges such as coupling effects between

Energy Internet, EarlyView.ABSTRACT Extreme icing disasters increasingly undermine the reliability of integrated power and heat networks by causing line outages, supply shortages and sharp thermal load fluctuations. To address these challenges, this paper proposes a comprehensive optimisation framework that exploits the spatiotemporal flexibility of data centres for coordinated ...

High Voltage, EarlyView.ABSTRACT Infrared and visible image registration is a key task in automated distribution network inspection. Previous approaches typically apply a single homography to align infrared and visible images leading to local misalignment. To address this, this study proposes a novel region‐based registration algorithm specifically designed for wide‐depth ...

British Journal of Special Education, EarlyView.Abstract Parents of children with special needs in Nigeria are faced with several challenges. In most cases, decisions are taken without their active involvement, despite them being the primary carers for their children with special needs. This research utilised a qualitative research design with fifteen participants to understand parents' perspectives
