Application of compressive sensing to tow-way relay channel estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
An Amplify and Forward Two-Way Relay Network is one where two nodes transmit data to
each other via an intermediate relay. The relay amplifies the superimposed data from both
the nodes before sending it to both the nodes. ...
Application of network coding in wireless sensor and relay based ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Network Coding (NC) is a new area which brings radical change in the way we
treat information flow in networks. NC considered being a layer 3 operation has been
shown to improve the throughput of wired networks especially ...
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 ...
Design of a novel high linearity down conversion mixer for GSM band applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Double balanced Gilbert cell mixer (GCM) is the mostly used kind of mixer as it provides
conversion gain and has port to port isolation. This mixer lacks in linearity and noise figure
which are to be taken care in designing ...
Design of digital accelerometer based seismic sensor node
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The aim of Design of Digital Accelerometer based Seismic Sensor Node is to propose a design for wireless sensor network for exploring the sub-surface region of the moon by studying the seismic waves generated over there. ...
Distributed clustering for heterogeneous wireless sensor network in data gathering applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Wireless Sensor networks have revolutionized the paradigm of gathering and processing data in diverse environment such as, wildlife area, kindergarten or agriculture farm. The nodes in these networks usually have a very ...
Energy efficient data gathering protocol for wireless sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Wireless Sensor Network is made up of hundreds and thousands of miniature electronic devices called node, which have sensors built on them. Functionality of a sensor is entirely application dependent. They can perform a ...
