Novel architecture for a CMOS low noise amplifier at 2.4 GHz
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Radio frequency design has been one of the major research areas in the recent past. Emergence of several Wireless Communication standards has demanded availability of different analog blocks for use in transceivers with ...
Optimum network utilization using fortz-thorup method
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Internet traffic has increased over the previous years and there has been a change in traffic requirements due to the emergence of new applications and services. This makes it more challenging for the network service ...
Performance evaluation of OFDM technique for high speed communication applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
The Internet revolution has created the need for wireless technologies that can deliver data at high speeds in a spectrally efficient manner. However, supporting such high data rates with sufficient robustness to radio ...
Performance of MIMO in correlated rayleigh flat fading channels
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
The recent interest in Multiple Input Multiple Output (MIMO) communication systems was initiated by the theoretical work of Telatar. The development in the field of random matrix theory is the basis of these studies. The ...
Protecting structures on heap from buffer overflow vulnerabilities with TIED-LibsafePlus
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
In spite of the numerous defenses that have been devised to combat the buffer overflow attack, buffer overflow vulnerability in the C programs still exist as the one widely exploited by the attackers to subsume the privileges ...
Representation theory in signal processing: some connections through gap
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
This thesis is concerned with the study of some of the recent developments in the area of signal processing that arise from the connections of discrete transforms and their inherent symmetries with the representation theory ...
Scheduling in grid: rescheduling MPI applications using a fault-tolerant MPI implementation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Due to advancement in grid technologies, resources spread across the globe can be accessed using standard general purpose protocols. Simulations and scientific experiments were earlier restricted due to limited availability ...
Acoustic source localization using audio and video sensors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Problem of localizing an acoustic source using microphone array and video camera is studied. In general, it’s quite obvious that a human with both, eyes and ears can make out things more accurately than to a human who is ...
Design of laser driver circuit
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Designing an Optoelectronic Integrated Circuit (OEIC) is an attractive field of research as it bridges the interface between electrical and optical components. The design of laser driver in optical transmitter is very ...
Enhancing data efficiency in OFDM (IEEE 802.11a) using equalization (11A)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
IEEE 802.11a OFDM signal passed through a dispersive channel introduces ISI & ICI. To avoid ISI & ICI, cyclic prefix (guard interval) is introduced between the OFDM symbols. But the cyclic prefix contributes about 20% ...
