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 ...
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), ...
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 ...
Low power microprocessor design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This research work tries to reduce the power consumption of a processor with signal processing features. For low power design, focus is on developing ‘Low power synthesizable Register File’, as the initial study shows that ...
Spectral estimation using WRLS algorithm for multiband detection
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Signal parameter estimation in the presence of noise has been a key area of research. Many applications have benefited from advancements made in this field within the last two decades. The method proposed in the thesis ...
Video compression using color transfer based on motion estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Many compression techniques were developed in last decade and are being used in many applications like HDTV, Videoconferencing, Videophone, multimedia work stations and mobile image communications. It is also certain that ...
Design of low power and high speed decoder for 1MB memory
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Technology scaling is accompanied by rise in leakage power dissipation. This thesis proposes a voltage controllable circuit in the feedback path of the decoder, which drastically reduces the standby leakage current with ...
Study of algebraic and state based testing techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Sequential programs can be modeled as algebra or transitions on a state space. Whether a program is implemented according to its model is the question addressed by program testing. The thesis illustrates issues in constructing ...
