The Combined Effect Of Reduced Feedback, Frequency-Domain Scheduling, And Multiple Antenna Techniques On The Performance Of LTE
(2014-11-21)Frequency-domain scheduling, multiple antenna techniques, and rate adaptation enable next generation orthogonal frequency division multiple access (OFDMA) cellular systems such as Long Term Evolution (LTE) to achieve ... -
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 ... -
Compression for Distributed Optimization and Timely Updates
The goal of this thesis is to study the compression problems arising in distributed computing systematically. In the first part of the thesis, we study gradient compression for distributed first-order optimization. We ... -
Computational Models of Perceptual Space : From Simple Features to Complex Shapes
(2018-02-15)Dissimilarity plays a very important role in object recognition. But, finding perceptual dissimilarity between objects is non-trivial as it is not equivalent to the pixel dissimilarity between the objects (For example, two ... -
Computer recognition of hand printed characters: an automated approach to the design of recognizers
Computer Recognition of Handprinted Characters is a well-established field of research, active for over three decades. Despite extensive work and numerous publications, the ultimate goal of developing a recognizer with ... -
Conformal Active Sheets
(2017-12-16)Stretchable Electronics is an emerging class of electronics that allow electronics to be bent, conform, ex and stretch while still retaining its full functionality. Other than bending, existing and conforming, adding ... -
Constellation Constrained Capacity For Two-User Broadcast Channels
(2011-07-12)A Broadcast Channel is a communication path between a single source and two or more receivers or users. The source intends to communicate independent information to the users. A particular case of interest is the Gaussian ... -
Constrained virtual path routing algorithms in packet networks
We presented a new algorithm for on-line routing of Virtual Paths in a packet network. The main application of the algorithm is in explicit routing o f LSPs in MPLS networks. We modeled the routing problem as a mixed ... -

Contributions on Index Coding, Coded Caching and Gradient Coding
In this thesis, we cover three major areas, namely, index coding, coded caching and gradient coding. We begin by considering unicast index coding problems where a server broadcasts coded messages over a noiseless channel, ... -
Cooperative Communication and QoS in Infrastructure WLANs
(2018-05-08)IEEE 802.11 wireless LANs operating in the infrastructure mode are extremely popular and have seen widespread deployment because of their convenience and cost efficiency. A large number of research studies have investigated ... -
Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ... -
Cooperative Communication Protocols : Diversity-Multiplexing Gain Tradeoff And Code Constructions
(2009-05-19)Cooperative relay communication is a promising means of wireless communication in which cooperation is used to create a virtual transmit array between the source and the destination, thereby providing spatial diversity for ... -
Coplanar Capacitive Coupled Probe Fed Ultra-Wideband Microstrip Antennas
(2010-12-07)Modern wireless communication systems call for ultra wideband operations to meet the continuous growth in the number of users of these systems. Since antenna is an integral part of any wireless communication system ... -
Correlation-aware Splitting Algorithms for Opportunistic Selection
Opportunistic selection is a key technique to improve the performance of wireless systems. In it, the best set of users among the available ones is selected on the basis of their instantaneous channel gains or local ... -
Data communication in the presence of atomospheric noise bursts
At tropical latitudes, atmospheric noise bursts constitute an important interference to digital communication. The characteristics of these noise bursts have been extensively studied in the LF, MF and HF bands. Satisfactory ... -
