Outage performance of OFDM-based relaying systems under IQ imbalance

, 2013
In the presence of different IQ imbalance (IQI) levels in the different nodes of a cooperative system, it becomes necessary to investigate the effect of each imbalance parameter on the performance.

Probing the Energy Trilemma Pillars: Do Innovation Pathways Deliver Cleaner and More Equitable Energy Systems?

Sustainable Development, EarlyView.
ABSTRACT Balancing reliable energy supply, equitable access, and environmental sustainability is a central challenge of the global energy transition. This study examines how innovation influences the energy trilemma by shaping energy security, energy equity, and environmental sustainability across 115 countries from 2011 to 2023.

Practical Methodology for Developing Visions for Carbon‐Neutral Cities and Communities

Sustainable Development, EarlyView.
ABSTRACT Cities and communities play important roles in sustainable development and climate change mitigation. This study presents a novel framework for developing carbon‐neutral visions for cities and communities. We established five “principles,” investigated options encompassing four parameters (management, goal setting, actions, and quantification),

Unravelling Cascading Phenomena in Sociotechnical Systems: A Systematic Review and Modelling Framework

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article investigates the characterization of cascading phenomena within sociotechnical systems through a systematic review and the development of a conceptual modelling framework. Cascading phenomena, often described using terms such as ripple effect, domino effect, cascading failure, risk propagation and cascading effect, capture the far‐

Outage Exponent for OFDM Channels

, 2010
OFDM is playing a more and more important role in wireless communication systems. Unfortunately, it is not trivial to conduct a performance analysis of OFDM systems. Therefore, it is highly desired to develop an analytical design and performance analysis
