Charge Density Wave-driven Carrier Transport in Layered Heterostructures
Metal-based electronics remain one of the longstanding goals of researchers to achieve ultra-fast and radiation-hard electronic circuits. Generally, metals are primarily used as passive conductors in modern electronics and ...
Inverse Problems in 3D Full-wave Electromagnetics
An inverse problem in Electromagnetics (EM) refers to the process of reconstructing the physical system by processing the measured data of its electromagnetic properties. Inverse problems are typically ill-posed, and this ...
Correlation-aware Splitting Algorithms for Opportunistic Selection
Opportunistic selection is a key technique to improve the performance of wireless systems. In it, the best set of users among the available ones is selected on the basis of their instantaneous channel gains or local ...
Integrated optic devices on thin film lithium niobate for few-mode optical communications
Mode division multiplexing is a remarkable strategy to meet the explosively increasing
bandwidth requirements in optical communication systems and interconnects. This scheme
harnesses the orthogonality of modes to scale ...
Design of Privacy Protection Schemes for Mobile Adhoc Networks using Rough Set Theory
MANET is a self-con guring, decentralized and infrastructure-less mobile wireless network,
where autonomous mobile nodes (such as laptops, smartphones, sensors, etc.) communicate
over the wireless channels. Thus, MANETs ...
Optimal Code Constructions for Some Multi-sender Index Coding Problems
An instance of the multi-sender index coding problem consists of a set of senders
collectively having all the messages demanded by a set of receivers. Each receiver
knows a subset of messages a priori, called its side ...
Error Correction in Index Coding And Coded Caching
In an index coding problem, there is a sender which has a set of messages and there
are multiple receivers demanding possibly different subsets of these messages and
possessing some other subsets of these messages as ...
Synthesis of Conformal Antenna Arrays on Polygonal Cross-Sectional Cylindrical Conductors for 360 Degree Azimuth Coverage Applications
Antenna arrays are one of the most important part of any RF communications system nowadays.
Ranging from military to communication applications, the versatility they provide in selectively
enhancing and rejecting signals ...
Underwater Acoustic Communications: Algorithms for Delay-Scale Spread Wideband Channels
In wideband wireless communication systems, the relative motion of the transmitter, receiver, or scatterers in the medium causes the Doppler effect, which stretches or compresses the transmitted waveforms, resulting in ...
Codes With Combined Locality and Regeneration Having Optimal Minimum Distance and Linear Field Size
This thesis presents error correcting codes in the setting of distributed storage. The codes presented in this thesis are optimal with respect to the minimum distance bound and have a finite field size which grows ...
