Analysis of nonlinearity in speech production mechanism for speaker verification: phase-based approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Many of the real-world signal processing problems can be described using linear models, and can be realized as analog or digital filter, time-invariant filters; finite or infinite impulse response (IIR or FIR) filters. In ...
Application of compressive sensing to tow-way relay channel estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
An Amplify and Forward Two-Way Relay Network is one where two nodes transmit data to
each other via an intermediate relay. The relay amplifies the superimposed data from both
the nodes before sending it to both the nodes. ...
Analysis of charge injection in a MOS analog switch with impedance on source side
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Turning off of a transistor introduces error voltage at the output of Sample and Hold circuits
which are the key components of Analog to Digital Converters (ADCs) and hence limits their
accuracy of performance in high ...
Application of network coding in wireless sensor and relay based ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Network Coding (NC) is a new area which brings radical change in the way we
treat information flow in networks. NC considered being a layer 3 operation has been
shown to improve the throughput of wired networks especially ...
Approach for scalability in software as a service
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Software as a Service (SaaS) is a software service delivery model. Software is centrally hosted on cloud infrastructure and delivered as a service through the Internet. Scalability is one of the major issues in SaaS. One ...
Analysis of various DFT techniques in the ASIC designs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
With the increasing demand of mobile communication industry and highly progressive VLSI technology, muti-million gates silicon chips are in the market. And to have fault free, reliable chips, extended facility of testable ...
Automatic brain tumour segmentation using rough sets
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Brain tumour segmentation is an important research topic in computer assistedmedical intervention. Automation of this process ensures that valuable expertresources are made available to a wider range of people and more ...
Automatic speech recognition using deep neural networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Automatic Speech Recognition (ASR) is an important field of research because ofits widespread use in various fields such as military, health services, day-to-dayactivities, etc. ASR task was earlier done using GMM-HMM ...
Back-view based visual hand gesture recognition system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Gesture recognition is a fascinating area of research due to its applications to HCI
(human computer interaction), entertainment, and communication between deaf/ mute people etc. Gesture can be dynamic or static depending ...
Authorship attribution using quantitative analysis of languages.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this work we propose a Kullback Liebler Divergence based method for authorship attribution. We examine several quantitative techniques of authorship attribution that have gained importance over the time including the ...
