Bayesian Techniques for Joint Sparse Signal Recovery: Theory and Algorithms
This thesis contributes new theoretical results, solution concepts, and algorithms concerning the Bayesian recovery of multiple joint sparse vectors from noisy and underdetermined linear measurements. The thesis is written ... -
Capacity Computation and Coding for Input-Constrained Channels
The setting of the transmission of information over noisy, binary-input, memoryless channels is today well-understood, owing to the work of several information theorists, beginning with Claude Shannon. It is known that it ... -
Design of Non-Cartesian k-space Trajectories for Reduced Scan Time in Magnetic Resonance Imaging Systems
Magnetic resonance imaging (MRI) is a non-invasive and safe medical imaging technique. This imaging modality collects samples in the Fourier domain, called as the k-space. The k-space is traversed along continuous trajectories ... -
Designing Solutions to Counter the Attacks in Mobile Ad hoc Networks
The open medium, dynamic topology and distributed operation in Mobile Ad hoc Networks (MANET) leads to high risks. Many solutions are proposed to protect a MANET from attacks, ranging from attack identification to ... -
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 ... -
Index Coding, Error Correcting Index Codes And Matroids
In the problem of index coding, there is a central source sending messages to a set of receivers which demand messages over a noiseless broadcast channel. Each receiver knows a subset of messages which is referred to as ... -
On Reduced-State Optimal Scheduling for Decentralized Medium Access Control of Wireless Data Collection Networks
In the Internet of Things (IoT), devices such as sensors and actuators will almost invariably be connected to the Internet via wireless networks. The sensor and actuator devices in such systems will be resource challenged ... -
Reinforcement Learning in Large and Structured Environments
In a reinforcement learning (RL) problem, a learner takes actions to control the state of an initially unknown environment so as to maximize the sum of the rewards he obtains. This has several applications in many practical ... -
Revealing Disocclusions in Temporal View Synthesis
We consider the problem of temporal view synthesis, where the goal is to predict a future video frame from the past frames using knowledge of the depth and relative camera motion. The problem has applications in frame rate ... -
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 ... -
Tailoring excitonic complexes in layered materials
Layered transition metal dichalcogenides (TMDCs) host a variety of strongly bound exciton complexes that control the optical properties in these materials. Apart from spin and valley, layer index provides an additional ... -
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, ... -
True Random Number Generators based on Amplified Spontaneous Emission
Low-cost, high-speed quantum random number generators (QRNGs) are imperative to develop in order to have a widespread application in areas ranging from cryptography and stochastic simulations to banking and internet. ...
