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 ...
Cooperation enforcement mechanisms in wireless adhoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Wireless adhoc networks are autonomous, infrastrutureless networks where there are no dedicated routers or base stations and nodes are expected to cooperate in Wireless performing routing duties to keep network connected. ...
Design and implementation of 128-point fixed point streaming FFT processor for OFDM based communication system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Fast Fourier Transform (FFT) processors are today one of the most important blocks in communication systems. They are used in every communication system from broadband to 3G and digital TV to Radio LANs. This master’s ...

The communication system using the OFDM principle is today one of the most important application in communication field. This system has various applications from broadband to 3G and digital TV to Radio LANs. This master’s ...
Identifying small world network properties in ad-hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Small World Network is a densely connected network with low degree of separation. These types of networks have high clustering property like regular network as well as have low average path length like random network. Thus, ...
Issues of computational resource allocation and load balancing in cloud computing using virtualization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
With the advent of world wide web, the life of every person has changed drastically. No one can imagine a computer without being connected to the Internet. This dependency is likely to grow in coming years with the adoption ...
Low drop-out (LDO) voltage regulator without off-chip capacitor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Designing of Low Drop-Out Voltage Regulators (LDOs) operating without a large off-chip capacitor, having a very good transient response and maintaining the loop stability for full load current range in low supply voltage ...
On size balanced binary search trees
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
History independent data structures are useful when security and privacy are of primary concern. Even if an adversary gets copy of the data structure, he cannot obtain any additional information beyond its content. Important ...
Path complexity of the class binary search tree
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Path complexity of a program is defined as the number of program execution paths as a function of input size n. This notion of program complexity has been extended to complexity of a class as follows. Class had data members ...
Self-calibrating technique for digital-to-analog converter in successive approximation register analog-to-digital converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Successive Approximation Register (SAR) analog to digital converter resolution is limited mainly by the capacitor ratio error; comparator offset voltage and capacitor voltage dependence error. A SAR ADC resolution is limited ...
