Weblab: a framework for remote laboratories
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Remote laboratories have been proposed and implemented in the past to address a number of issues, namely wider access to high-end expensive experiments, safety, and better resource utilization. However, the existing projects ...
A 0.18µ low power dual-mode transceiver front-end design for high speed bluetooth systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Today’s market trend is to possess a single multi-purpose, multi-functional personal device for various wireless personal area network (WPAN) applications. So it raises a great demand to develop multi-mode/multi-standard ...
Active contours in action
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
There was considerable success in converting images into something like line drawings without resorting to any but the most general prior knowledge about smoothness and continuity. That led to the problem of “grouping” ...
Analysis of address allocation protocols for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In almost all networks, it is necessary to have a unique identifier for each node. This identifier is used to find out route locating a particular node. So an address is must for any node for unicast communication. Addresses ...
Adaptive biased switched capacitor filters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
The demand from today’s handheld devices, such as laptop, ipod, cellphones is to have a long battery life with no compromises in speed. The devices dissipate power even in standby mode also. Op-amp is a major block in all ...
Application of BTrees in data mining
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
As massive amount of information are becoming available electronically, techniques for making the decision to analyze statistics on the large dataset are tending to be very complex. Making of such a decision requires more ...
Area reduction in 8 bit binary DAC using current multiplication
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
A proposed current multiplication technique is applied on 8 bit binary current steering Digital-to -Analog Converters with LSB 150 μA, to reduce area. MSB 1 and MSB 2 current are first kept half to reduce area and then ...
Automated categorization of structured documents
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Automatic text categorization is a problem of assigning text documents to pre¬-defined categories. This requires extraction of useful features. In most of the applications, text document features are commonly represented ...
Built-in self test architecture for mixed signal systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Built-in self test architecture or BIST as we call them, are the necessity of time since the shrinking sizes of component on-chip with advance in IC technology are making it BIST artistries are being rapidly developed and ...
Channel estimation and tracking OFDM and MIMO systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In this thesis, To estimate and track the slow Time varying channels in OFDM and MIMO systems. In first part: we have used a two-dimensional recursive least square adaptive channel estimation technique is used. In orthogonal ...
