Variational Bayes Algorithms for mmWave and Massive MIMO-OFDM Systems with Low Resolution ADCs
In this thesis, we develop novel low-complexity algorithms for massive multiple-input multiple-output (MIMO) systems under practical non-idealities and theoretically analyze their performance. The first problem we consider ...
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 ...
Adjacent Independent Row (Air) Matrices and Index Coding
An index coding problem, comprises a transmitter that has a set of independent
messages and a set of receivers. Each receiver knows a subset of messages, called
its side-information, and demands another subset of messages, ...
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 ...
Efficient Resource Allocation for Underlay Device-to-device Communication Networks with Limited Channel State Information
Device-to-device (D2D) communication is finding applications in future wireless networks such as vehicular networks and internet-of-things. It offloads traffic from the base station (BS), improves energy efficiency, and ...
Opportunistic Beamforming and Asymptotic Throughput Analysis of Hybrid Analog-Digital mmWave Multi-User MIMO Systems
In this thesis, we address the problem of large training/feedback overhead and the requirement
of computationally intensive algorithms to determine the phase angles of the analog
precoder for downlink data transmission ...
Nonlinear Optical Enhancement Studies in Silicon-based Resonant Metasurfaces
Metasurfaces are two dimensional arrangements of building blocks called meta-atoms which have been found to be useful to manipulate amplitude, phase, polarization of light at the nanoscale. Using these properties, functional ...
Perceptual Quality Assessment of Lowlight Restored and Authentically Distorted Images
The capability of hand-held devices to acquire high-definition visual content has led to a tremendous increase in the number of images and videos captured daily. However, camera hardware and pipelines are not perfect and ...
Imitation Learning Techniques for Robot Manipulation
Robots that can operate in unstructured environments and collaborate with humans play a major role in raising productivity and living standards as societies age. Unlike the robots currently used in industrial settings for ...
Hybrid Electromagnetic Solvers for EMIEMC
With advances in technology and increased design complexity in the automotive
industry, Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC)
issues are becoming increasingly important. An accurate ...
