Resource Allocation Schemes for 4G/5G based Interactive Multimedia Networks
Emerging interactive multimedia applications such as Virtual Reality (VR) and Augmented Reality are upcoming important applications in healthcare, autonomous transport, education, tactile internet, and industrial automation. ...
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, ...
Risk Estimation Strategies for Speech Signal Denoising
In automatic speech recognition (ASR) systems, the recognition performance is severely
affected by noise in the input speech signal [2]. One can improve the performance of ASR
systems in noisy environments by denoising ...
Compositionality of Object Representations in Brains and Machines
Compositionality in object vision can be defined as the principles governing the
relationship between whole objects and their constituent attributes. It is known that object
information falling on the retina is processed ...
Probabilistic Forwarding of Coded Packets for Broadcasting over Networks
Motivated by applications in sensor networks and the Internet of Things (IoT), in this dissertation, we consider the problem of energy-efficient broadcasting from a source node in a large dense network. Flooding, as a ...
Structured Sparse Signal Recovery for mmWave Channel Estimation: Intra-vector Correlation and Modulo Compressed Sensing
This thesis contributes new theoretical results and recovery algorithms for the area of sparse signal recovery motivated by applications to the problem of channel estimation in mmWave communication systems.
The presentation ...
Design and Analysis of Integrated Optic Waveguide Grating for Sensor and Communication Applications
Waveguide gratings are widely being used for multitude of applications owing to high sensitivity,
immunity to electromagnetic interference, multiplexing capabilities, light weight and compactness.
Waveguide gratings on ...
Design and Analysis of Full-duplex Systems for Next-generation Wireless Communication Systems
To cater to the ever-growing demand for higher data rates, cellular networks and
wireless local area networks (WLANs) need to adopt innovative technologies. Full-duplex
(FD) is one such technology that promises to double ...
Tailoring optical and electrical characteristics of layered materials through van der Waals heterojunctions
The feasibility of isolation of layered materials and arbitrary stacking of different materials provide plenty of opportunities to realize van der Waals heterostructures (vdWhs) with desired characteristics. In this thesis, ...
Support Recovery from Linear Measurements: Tradeoffs in the Measurement-Constrained Regime
In this thesis, we study problems under the theme of discovering joint sparsity structure in a set of high-dimensional data samples from linear measurements. Our primary focus is on the regime where the number of samples ...
