Coded Caching in Multi-access Networks
Caching is a promising technique that can reduce the amount of data transmitted over latency-prone links, effectively trading affordable memory for expensive bandwidth resources. The frequently demanded content is stored ... -
Codes for distributed storage, private information retrieval and low-latency streaming
This thesis presents results on error correcting codes for settings such as: (a) distributed storage, (b) private information retrieval, and (c) low-latency streaming. It also presents two new decoding algorithms for Polar ... -
Codes With Combined Locality and Regeneration Having Optimal Minimum Distance and Linear Field Size
This thesis presents error correcting codes in the setting of distributed storage. The codes presented in this thesis are optimal with respect to the minimum distance bound and have a finite field size which grows ... -
Codes With Locality For Distributed Data Storage
(2017-07-26)This thesis deals with the problem of code design in the setting of distributed storage systems consisting of multiple storage nodes, storing many different data les. A primary goal in such systems is the efficient repair ... -

Coding Schemes For Distributed Subspace Computation, Distributed Storage And Local Correctability
(2017-07-24)In this thesis, three problems have been considered and new coding schemes have been devised for each of them. The first is related to distributed function computation, the second to coding for distributed storage and the ... -
Coding Schemes for Secure and Reliable DNA-Based Data Storage
In DNA-based data storage, the desired information is encoded into the quaternary sequence of synthetic DNA molecules, called oligos. We look at secure communication via information-containing oligos in the usual three-party ... -
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 ... -
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 ... -
