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 ...
Data Fusion Based Physical Layer Protocols for Cognitive Radio Applications
(2017-09-26)
This thesis proposes and analyzes data fusion algorithms that operate on the physical layer of a wireless sensor network, in the context of three applications of cognitive radios: 1. Cooperative spectrum sensing via binary ...
Neuronal Dissimilarity Indices that Predict Oddball Detection in Behaviour
(2017-09-23)
Our vision is as yet unsurpassed by machines because of the sophisticated representations of objects in our brains. This representation is vastly different from a pixel-based representation used in machine storages. It is ...
Distributed Algorithms for Power Allocation Games on Gaussian Interference Channels
(2017-09-20)
We consider a wireless communication system in which there are N transmitter-receiver pairs and each transmitter wants to communicate with its corresponding receiver. This is modelled as an interference channel. We propose ...
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 ...
Fundamentals Limits Of Communication In Interference Limited Environments
(2017-08-21)
In multiuser wireless communications, interference not only limits the performance of the system, but also allows users to eavesdrop on other users’ messages. Hence, interference management in multiuser wireless communication ...
Spectrum Sensing Techniques For Cognitive Radio Applications
(2017-07-25)
Cognitive Radio (CR) has received tremendous research attention over the past decade, both in the academia and industry, as it is envisioned as a promising solution to the problem of spectrum scarcity. ACR is a device that ...
Finding A Subset Of Non-defective Items From A Large Population : Fundamental Limits And Efficient Algorithms
(2017-07-12)
Consider a large population containing a small number of defective items. A commonly
encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) ...
Delay Differentiation By Balancing Weighted Queue Lengths
(2017-05-04)
Scheduling policies adopted for statistical multiplexing should provide delay differentiation between different traffic classes, where each class represents an aggregate traffic of individual applications having same ...
Low Power And Low Spur Frequency Synthesizer Circuit Techniques For Energy Efficient Wireless Transmitters
(2017-09-07)
There has been a huge rise in interest in the design of energy efficient wireless sensor networks (WSN) and body area networks (BAN) with the advent of many new applications over the last few decades. The number of sensor ...
