Equalization Algorithms And Performance Analysis In Cyclic-Prefixed Single Carrier And Multicarrier Wireless Systems
(2014-05-21)The work reported in this thesis is divided in to two parts. In the first part, we report a closed-form bit error rate (BER) performance analysis of orthogonal frequency division multiple access (OFDMA) on the uplink in ... -
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 ... -
Erasure Codes for Distributed Storage: Tight Bounds and Matching Constructions
The reliable storage of Big Data across a spatially distributed network of nodes, calls for erasure-correcting codes that in addition to protecting against data loss, can also efficiently handle node repair. The need for ... -
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 ... -
Errors In Delay Differentiation In Statistical Multiplexing
(2010-03-03)Different applications of communication networks have different requirements that depend on the type of application. We consider the problem of differentiating between delay-sensitive applications based on their average ... -
Estimation Of Object Shape From Scattered Field
(Indian Institute of Science, 2005-09-27)The scattered field from an object, when illuminated with ultrasound, is useful in the reconstruction of it's cross section - a problem broadly classified as 'tomography'. In many situations of medical imaging, we will ... -
Excitonic complexes in semiconducting monolayers and their twisted heterojunctions
Monolayers of transition metal dichalcogenides (TMDCs) host excitons, a bound state of electron and hole. Excitonic many-body complexes dominate the optical spectra obtained from this system and manipulating these complexes ... -
Excitons in monolayer transition metal dichalcogenides
Excitons are quasiparticles formed due to electrostatic attraction between the electrons and the holes in a semiconductor. This Coulomb attraction is very strong in the mono- layers of Transition Metal Dichalcogenides ... -
Exploration of Displacement Detection Mechanisms in MEMS Sensors
(2017-11-14)MEMS Sensors are widely used for sensing inertial displacements. The displacements arising out of acceleration /Coriolis effect are typically in the range of 1 nm-1 m. This work investigates the realization of high resolution ... -
Exploring the Fundamental Limits of Information-Theoretically Secure Key Generation and DNA-Based Data Storage
In this dissertation, we carry out an exploration of the fundamental limits of information-theoretic security in two different settings: multiterminal key agreement and DNA-based data storage. Most of the dissertation ... -
