FM based pipeline ADC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
This thesis aims at designing a new architecture for an FM based pipelined Analog to Digital Converter (ADC). It is based on the fact that power is a function of voltage and therefore handling with voltage becomes a difficult ...
Routing and wavelength assignment in DWDM networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
All-Optical Networks employing Dense Wavelength Division Multiplexing (DWDM) are believed to be the next generation networks that can meet the ever-increasing demand for bandwidth of the end users. The problem of Routing ...
Secure data delivery in mobile ad hoc network using multiple paths
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
A mobile ad hoc network (MANET) is a self configurable, self organized, infrastructure less multi hop mobile wireless network.Characteristics of ad hoc network make security a critical issue i.e. any node can join the ...
Reconstruction of 1-D signal from the undersampled version
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In the present era of information the data transmission and data storage are done as per the sampling theorem. The sampling theorem states that a bandlimited signal has to be sampled at a rate two times the maximum frequency ...
Channel quality prediction and localization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
In this thesis we focus on two problems, Channel Quality Prediction and Localization in wireless network. In High-Speed Downlink Packet Access (HSDPA) architecture of Universal Mobile Telecommunications Services (UMTS), ...
Development of difference detection algorithm for surveillance video compression
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Video surveillance is widely used tool in today’s era for improving public and residential safety. Here the size of the video data is much higher due to large number of surveillance cameras scattered over large area and ...
Timing aware asic design flow (RC physical)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Lack of communication between frontend and backend designers is the most important issue in today�s ASIC (Application Specific Integrated Circuits) design. The frontend designers lack knowledge about the long wires which ...
Physical layer network coding in relay assisted OFDM based wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Relays have the potential to support transmissions over long distance ranges, much more<p/>than what can be accomplished by relay-less wireless networks. The concept of network coding<p/>(NC) that was originally conceived ...
Shorted microstrip patch antenna
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
In this thesis, electrically small microstrip patches incorporating shorting posts are thoroughly investigated. These antennas are suitable for mobile communications handsets where limited antenna size is a premium. In ...
Buffer aware routing in interplanetary ad hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Recent research has shown that existing TCP/IP protocol suit exhibits poor performance in space communication networks. To deal with communication challenges in deep space such as long propagation delay, high channel error ...
