Design of narrowband and wideband low noise amplifier for RADAR applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
This thesis reviews and analyze the designing of Low Noise Amplifier (LNA) inX-band. X-band frequencies are mostly used in RADAR receivers. The transistorused for design is GaAs FET because of its better performance at ...
Desing of RF front-end receiver sub-system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
A Radio Frequency(RF) front end receiver subsystems; Low Noise Amplifier(LNA) and mixer is designed at RF frequency of 2.45GHz. The main design aim of LNA is to enhance the performance parameters, especially to minimise ...
Distributed medium access control (MAC) protocol at 60 GHz for outdoor wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Growing demands of high bandwidth and data rates in wireless networks haveinspired the US Federal Commission Council (FCC) to free the licensed 60 GHzspectrum for emerging technologies. Typically, wireless networks operate ...
Image authentication using genetic algorithm
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
With a widespread deployment of digital images, there is need to authenticatesuch images for their originality and integrity.The main objective of the work is todesign an authentication scheme that allows two parties to ...
Novel nonlinear prediction-based features for spoofed speech detection
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Automatic Speaker Verification (ASV) systems are prone to various spoofing attacks.<p/>Spoofing is one type of technique in which fake speech signal is given to<p/>the ASV system to get the access of that system without ...
