Improved GMM-Based Classification Of Music Instrument Sounds
(2009-03-19)This thesis concerns with the recognition of music instruments from isolated notes. Music instrument recognition is a relatively nascent problem fast gaining importance not only because of the academic value the problem ... -
Influence Dynamics on Social Networks
(2018-02-15)With online social networks such as Facebook and Twitter becoming globally popular, there is renewed interest in understanding the structural and dynamical properties of social networks. In this thesis we study several ... -
Information-rich Sampling of Time-varying Signals
Confrontation with signal non-stationarity is a rule rather than an exception in the analysis of natural signals, such as speech, animal vocalization, music, bio-medical, atmospheric, ans seismic signals. Interestingly, ... -
Insights into Network Coding Using Tools From Linear Algebra and Matroid Theory
Traditionally, the transmission of information through a network was carried out using store-and-forward techniques. This entails managing information bits in a network analogous to commodity flow, without mixing or combining ... -
Integrated Interfaces for Sensing Applications
(2017-12-13)Sensor interfaces are needed to communicate the measured real-world analog values to the base¬band digital processor. They are dominated by the presence of high accuracy, high resolution analog to digital converters (ADC) ... -
Integrated Optic Microring Resonator based Sub-μN force and Force and Acceleration Sensors
Microring resonators have rapidly emerged in the past few years as a new sensing platform for miniaturization of modern integrated optical devices. Ring resonator are having advantages of compactness, stability with ... -
Interference Cancelling Detectors In OFDMA/MIMO/Cooperative Communications
(2009-09-02)In this thesis, we focus on interference cancelling (IC) detectors for advanced communication systems. The contents of this thesis is divided into the following four parts: 1. Multiuser interference (MUI) cancellation in ... -
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ... -
Interference Modeling in Wireless Networks
(2017-10-26)Cognitive radio (CR) networks and heterogeneous cellular networks are promising approaches to satisfy the demand for higher data rates and better connectivity. A CR network increases the utilization of the radio spectrum ... -
Investigation of Multi-Axis Beam Steering using Diffraction Grating
Optical beam-steering is becoming a key optical functionality in free space optical links used for communication and sensing. For example, in recent times, compact, wide-angle, fast, multi-axis beam steering is used ... -
Joint Estimation of Impairments in MIMO-OFDM Systems
(2017-11-16)The integration of Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) techniques has become a preferred solution for the high rate wireless technologies due to its high spectral ... -
Joint Evaluation Of Multiple Speech Patterns For Speech Recognition And Training
(2009-12-09)Improving speech recognition performance in the presence of noise and interference continues to be a challenging problem. Automatic Speech Recognition (ASR) systems work well when the test and training conditions match. ... -
Joint Spectro-Temporal Analysis of Moving Acoustic Sources
Signals generated by fast moving acoustic sources are both challenging for analysis as well as rich in information. The motion is conceptually relative between the source and receiver i.e., either one of them is moving or ... -
Lambda Bipolar Transistor (LBT) in Static Random Access Memory Cell
(Indian Institute of Science, 2005-07-07)With a view to reduce the number of components in a Static Random Access Memory (SRAM) cell, the feasibility of use of Lambda Bipolar Transistor (LBT)in the bistable element of the cell has been explored under the present ... -

Lattice Codes for Secure Communication and Secret Key Generation
(2018-05-22)In this work, we study two problems in information-theoretic security. Firstly, we study a wireless network where two nodes want to securely exchange messages via an honest-but-curious bidirectional relay. There is no ...
