Frequency offset estimation in OFDM signals using particle filtering along with resampling methods
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Frequency offset is one of the main effects the Bit Error Rate(BER) in orthogonal frequency division multiplexing (OFDM). There are many applications which depend on OFDM. The present method describes the estimation of ...
Localization for a habitat monitoring sensor network for ground turtles
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis work deals with the localization problem (i.e. finding the location of the sensor nodes) in sensor networks. This work is specifically concerned with the localization of the sensor nodes on small ground turtles ...
Vehicle detection and tracking
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Real time trafficc monitoring is one of the most challenging problems in machine vision. This is one of the most sorted out research topic because of the wide spec-trum of promising applications in many areas such as smart ...
Design and implementation of a framework for context aware mobile services
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Applications designed for mobile platforms are traditionally hampered by the limita¬tions of the client devices, in particular limited user interface and the change of user environment due to mobility. Incorporating location ...
Performance analysis of fair schedulers under heterogeneous traffic
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
In this thesis, the role of the packet scheduling discipline has been studied in providing QoS over the Internet. The fairness and scalability requirements expected to be satisfied by the scheduling discipline have been ...
ASIC implementation of discrete fourier transform processing module
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This work presents the design and ASIC implementation of Discrete Fourier Transform Processing Module. The performance of designed DFT processing module is better than radix-2 and radix-4 FFT algorithms, and is comparable ...
Secure and efficient key assignment scheme for dynamic access control in a hierarchy
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
The users belonging to an organization are often assigned different access permissions depending on their security class. In this situation, the users belonging to a higher security class are allowed access to the information ...
Mobility aware MANET routing protocol using cross layer design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Mobile Adhoc Network (MANET) is a dynamic network with time varying topology and time varying network resources. Due to the error-prone wireless channel and high mobility, traditional protocols of wired networks cannot be ...
Practical approaches for photometric stereo
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
In this thesis work, we aim to propose approaches for photometric stereo that are less time consuming and have low computational requirements. Many applications of computer vision require high resolution 3-D structure of ...
Modeling MANETs using queuing networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mobile Ad Hoc Networks (MANETs) are becoming an attractive solution to the services that require flexible establishment, dynamic and low cost wireless connectivity. Since nodes are mobile, routing results vary significantly ...
