Timbre Perception of Time-Varying Signals
(2017-12-10)
Every auditory event provides an information-rich signal to the brain. The signal constitutes perceptual attributes of pitch, loudness, timbre, and also, conceptual attributes like location, emotions, meaning, etc. In the ...
Space-Time Block Codes With Low Sphere-Decoding Complexity
(2017-05-04)
One of the most popular ways to exploit the advantages of a multiple-input multiple-output (MIMO) system is using space time block coding. A space time block code (STBC) is a finite set of complex matrices whose entries ...
Bitrate Reduction Techniques for Low-Complexity Surveillance Video Coding
(2017-09-26)
High resolution surveillance video cameras are invaluable resources for effective crime prevention and forensic investigations. However, increasing communication bandwidth requirements of high definition surveillance videos ...
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 ...
Energy Harvesting Wireless Sensor Networks : Performance Evaluation And Trade-offs
(2017-09-23)
Wireless sensor networks(WSNs) have a diverse set of applications such as military surveillance, health and environmental monitoring, and home automation. Sensor nodes are equipped with pre-charged batteries, which drain ...
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 ...
