Classical Binary Codes And Subspace Codes in a Lattice Framework
(2017-10-10)The classical binary error correcting codes, and subspace codes for error correction in random network coding are two different forms of error control coding. We identify common features between these two forms and study ... -
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 ... -
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 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 ... -
Distributed Coding For Wireless Sensor Networks

Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ... -
Diversity-Mutiplexing Tradeoff Of Asynchronous Cooperative Relay Networks And Diversity Embedded Coding Schemes
(2010-08-23)This thesis consists of two parts addressing two different problems in fading channels. The first part deals with asynchronous cooperative relay communication. The assumption of nodes in a cooperative communication relay ... -
Efficient Constructions of Streaming Codes
Streaming codes are a class of erasure codes that operate on a stream of packets and enable recovery of dropped or erased packets under a decoding-delay constraint. The primary focus of this thesis is on providing constructions ... -
Guessing And Compression : A Large Deviations Approach
(2011-04-01)The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ... -
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ... -
Low Decoding Complexity Space-Time Block Codes For Point To Point MIMO Systems And Relay Networks
(2010-07-12)It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) ... -
Low-Complexity Decoding and Construction of Space-Time Block Codes
(2018-04-11)Space-Time Block Coding is an efficient communication technique used in multiple-input multiple-output wireless systems. The complexity with which a Space-Time Block Code (STBC) can be decoded is important from an ... -
Low-PAPR, Low-delay, High-Rate Space-Time Block Codes From Orthogonal Designs
(2011-02-03)It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. Some of the design criteria of the space-time block codes ... -
Network Coding for Wirless Relaying and Wireline Networks
(2017-12-10)Network coding has emerged as an attractive alternative to routing because of the through put improvement it provides by reducing the number of channel uses. In a wireless scenario, in addition, further improvement can be ... -
On Network Coding and Network-Error Correction
(2018-04-24)The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information flow networks. Network coding makes use of the fact that unlike physical commodities, ... -
