FPGA implementation of direct sequence spread spectrum techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This work presents the performance, noise analysis and FPGA implementation of Direct Sequence Spread Spectrum technique. Performance of signal increases as increasing parity bits in Hamming code algorithm. Increasing parity ...
Low cost design of IFFT module for dolby AC-3 decoder
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Dolby AC-3 is a flexible audio data compression technology capable of encoding a range of audio channel formats into a low rate bit stream. AC-3 is the de facto audio standard for high-end digital consumer multimedia ...
FPGA implementation of image compression algorithm using wavelet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This work presents FPGA implementation of image compression algorithm by using wavelet transform. Here the emphasis has been made on algorithmic encoding, the first step of image compression problem. The transform that has ...
Efficient ASIC implementation of advanced encryption standard
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In spite of the many defense techniques, software vulnerabilities like buffer overflow, format string vulnerability and integer vulnerability is still exploited by attackers. These software vulnerabilities arise due to ...
Study of bayesian learning of system characteristics
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis report basically deals with the scheduling algorithms implemented in our computer systems and about the creation of probabilistic network which predicts the behavior of system. The aim of this thesis is to ...
Use of probabilistic context free grammar for natural language interface for an application
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis report deals with the development of a natural language interface for a database application (library system). This application uses Probabilistic Context Free Grammar as a computation model. The material ...
