Real-Time Status Updates Over Erasure Channels
Real-time decision making relies on the availability of accurate data and, as such, delivering status updates in a timely fashion is of paramount importance. In this thesis, we first look at the interplay between average ... -
Reduced Feedback Schemes in 4g/5g Ofdm Systems: Modeling, Performance Analysis and Redesign
Reduced feedback schemes are a crucial component of orthogonal frequency division multiplexing-based 4G and 5G cellular systems that use downlink scheduling, adaptive modulation and coding, and multiple-input-multiple-output ... -
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 ... -
Relay Selection for Geographical Forwarding in Sleep-Wake Cycling Wireless Sensor Networks
(2018-04-11)Advances in wireless communication and microelectronics have led to the development of low-power compact sensor nodes (popularly called motes) that are capable of sensing, computing, and communication. A large number of ... -
Resource Allocation in Femtocells via Game Theory
(2018-08-14)Most of the cellular tra c (voice and data) is generated indoors. Due to attenuation from walls, quality of service (QoS) of di erent applications degrades for indoor tra c. Thus in order to provide QoS for such users the ... -

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. ... -
Resource Management In Celluar And Mobile Opportunistic Networks
(2015-01-07)In this thesis we study several resource management problems in two classes of wireless networks. The thesis is in two parts, the first being concerned with game theoretic approaches for cellular networks, and the second ... -
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 ... -
Reverse Channel Training in Multiple Antenna Time Division Duplex Systems
(2018-04-02)Multiple-Input Multiple-Output (MIMO) communication using multiple antennas has received significant attention in recent years, both in the academia and industry, as they offer additional spatial dimensions for high-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 ... -
Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading
(2018-07-16)Opportunistic use of unused spectrum could efficiently be carried out using the paradigm of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is not using it. The secondary nodes detect this ... -
Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems
(2013-10-04)The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ... -
