Optimal Relay Selection in Interference-Constrained Underlay Cooperative Cognitive Radio
Cognitive radio (CR) promises to significantly improve the utilization of scarce wireless spectrum. In the underlay mode of CR, which is the focus of the thesis, a secondary user (SU) can simultaneously transmit on the ...
Blocker-tolerant Receiver Design Suitable for Software-defined and Cognitive Radio Applications
The ever growing demand for higher data rates and the heavy usage of wireless communication devices have created frequency congestion on certain bands of the radio spectrum. The push has been towards new standards that can ...
Design of Communication Systems with Energy Harvesting Transmitters and Receivers
An energy harvesting node (EHN) operates using the energy harvested from the environment, e.g., solar, piezoelectric and radio frequency, which presents the tantalizing possibility of perpetually operating of sensor nodes. ...
Energy Aware Synthesis of Accelerators on a Network of HyperCells
With supply voltage no longer scaling down at the same rate as transistor feature size, keeping power dissipation to practical levels while maximizing performance is becoming a challenge in future computing systems. ...
Analysis and Control of Cascades in Complex Networks
Our modern societies are best described as complex systems consisting of a large number of interacting components. Understanding the nature of these interactions is crucial, not only for gaining insights, but also for ...
Unified Control based Adaptable Converters with a Fractional Harmonic Inter Converter Signalling channel for Dynamic tracking of PCC and Managing Multiple Converters Connected in Parallel in a Microgid
The increasing demand of energy over the past few years as well as the growing environmental
concerns have forced the mankind to look out for non conventional sources of
energy such as solar, wind etc. Consequently a ...
Safe Operating Area Reliability of AlGaN/GaN High Electron Mobility Transistors (HEMTs)
Gallium Nitride (GaN) based high electron mobility transistors (HEMTs) are extensively
considered for power switching and RF applications by the virtue of their unique
properties. However, despite of its attractive ...
Spatial Analysis and Reconstruction of Reverberant Speech
Speech signal includes the spoken message and a lot more information such as speaker emotion, identity, language, speaking location characteristic etc., which makes the human interaction lively, desirable and more useful. ...
Quantum-Drift-Diffusion Formalism Based Compact Model For Low Effective Mass Channel MOSFET
With the passage of time the semiconductor research community around the globe has progressed from a nearly four decades of dominating Silicon research to look for newer transistor materials, in the pursuit of more operating ...
Equivalent Circuit Analyses and Methods to Enhance Bandwidth of Klystron Reentrant Cavities
Klystron is used as an amplifier at microwave frequency range. Klystrons use cylindrical or rectangular reentrant cavities in their interaction structure. Characteristics of reentrant cavity can be defined using parameters ...
