Perceptual Criterion Based Rate Control And Fast Mode Search For Spatial Intra Prediction In Video Coding
(2010-03-11)This thesis dwells on two important problems in the field of video coding; namely rate control and spatial domain intra prediction. While the former is applicable generally to most video compression standards, the latter ... -
Towards Achieving Better NOx Removal In Discharge Plasma Treatment Of Diesel Engine Exhaust
(2010-03-03)In India, the expansion of industries and two-fold increase in motor vehicles over the last decade are posing a serious environmental crisis in the form of urban air pollution. Common pollutants include carbon monoxide, ... -
Errors In Delay Differentiation In Statistical Multiplexing
(2010-03-03)Different applications of communication networks have different requirements that depend on the type of application. We consider the problem of differentiating between delay-sensitive applications based on their average ... -
Time Management In Partitioned Systems
(2010-02-11)Time management is one of the critical modules of safety-critical systems. Applications need strong assurance from the operating system that their hard real-time requirements are met. Partitioned system has recently evolved ... -
Linear Network Coding For Wireline And Wireless Networks
(2010-02-10)Network Coding is a technique which looks beyond traditional store-and-forward approach followed by routers and switches in communication networks, and as an extension introduces maps termed as ‘local encoding kernels’ and ... -
FIR System Identification Using Higher Order Cumulants -A Generalized Approach
(Indian Institute of Science, 2010-01-12)The thesis presents algorithms based on a linear algebraic solution for the identification of the parameters of the FIR system using only higher order statistics when only the output of the system corrupted by additive ... -
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. ... -
Receiver Channelizer For FBWA System Confirming To WiMAX Standard
(2009-09-10)Fixed Broadband Wireless Access (FBWA) is a technology aimed at providing high-speed wireless Internet access, over a wide area, from devices such as personal computers and laptops. FBWA channels are defined in the range ... -
A New Family Of Soft Transition DC-DC Converters
(2009-09-10)Switched mode power supplies (SMPS) have found wide spread acceptance in all power processing applications. The design demand is moving towards higher power densities. For reduction in size and weight, it is imperative to ... -
A Peer To Peer Web Proxy Cache For Enterprise Networks
(2009-09-10)In this thesis, we propose a decentralized peer-to-peer (P2P) Web proxy cache for enterprise networks (ENs). Currently, enterprises use a centralized proxy-based Web cache, where a dedicated proxy server does the caching. ... -
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 ... -
Energy Efficient Scheduling Of Sensing Activity In Wireless Sensor Networks Using Information Coverage
(2009-08-19)Network lifetime is a key issue in wireless sensor networks where sensor nodes, distributed typically in remote/hostile sensing areas, are powered by finite energy batteries which are not easily replaced/recharged. Depletion ... -
Blind Detection Techniques For Spread Spectrum Audio Watermarking
(2009-08-13)In spreads pectrum (SS)watermarking of audio signals, since the watermark acts as an additive noise to the host audio signal, the most important challenge is to maintain perceptual transparency. Human perception is a very ... -
Music And Speech Analysis Using The 'Bach' Scale Filter-Bank
(2009-08-13)The aim of this thesis is to define a perceptual scale for the ‘Time-Frequency’ analysis of music signals. The equal tempered ‘Bach ’ scale is a suitable scale, since it covers most of the genres of music and the error is ... -
Low Correlation Sequences Over AM-PSK And QAM Constellations
(2009-08-13)Direct-Sequence Code Division Multiple Access (DS-CDMA), over the last few years, has become a popular technique and finds a place in many modern communication systems. The performance of this technique is closely linked ... -
Soft Switched Multi-Phase Tapped-Boost Converter And Its Control
(2009-08-04)Boost dc-to-dc converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the ... -
