Design issues in direct conversion receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
The wireless system is being rapidly proliferated in our life. The growing of capacity in wireless communication requires a new type of wireless communication method which does not affect current work on circuits and systems ...
Analysis and modeling of power distribution network and decoupling network design strategies for high speed digital and analog VLSI system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Today’s high speed digital and analog VLSI systems are operating in GHz frequency range. With high switching rate of the devices, power distribution network (PDN) impedance causes ripples in power supply. If PDN is not ...
Comparative study between exponential back off and dynamic waiting strategies for medium access in wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
IEEE 802.11 DCF (IEEE 802.11 Distributed Coordination Function) is widely used MAC protocol for wireless channel access. Although it is developed for single hop networks where all nodes are in the same radio range, it can ...
Design of CDMA transmitter and three finger rake receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
As cellular wireless communication becomes a worldwide communication standard, it is important in studying how data communications happens in a cellular system. In this Thesis work CDMA transmitter and receiver have been ...
Context aware semantic service discovery
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
This report is a part of an effort to develop a novel context based mechanism to facilitate semantic service discovery. Context- awareness is considered to be a key problem in designing more adaptive applications. Context ...
Routing game in wireless network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In this paper we have discussed about pricebased reliable routing in wireless AdHoc network.
<p/>Because of the selfish behavior of the nodes in the network the path chosen is not equilibrium path. We have considered the ...
Pulse shaping design for PAPR reduction in OFDM
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in todays cellular systems. By going to higher bandwidth the (for low bandwidth) at fading ...
Scheduling and isolation in virtualization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Virtual machine (VM) based server implementation is popular for numerous advantages like fault isolation, efficient hardware utilization, security and ease of management. Virtual machine monitor (VMM) like Xen is a popular ...
Analysis of address allocation protocols for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In almost all networks, it is necessary to have a unique identifier for each node. This identifier is used to find out route locating a particular node. So an address is must for any node for unicast communication. Addresses ...
Built-in self test architecture for mixed signal systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Built-in self test architecture or BIST as we call them, are the necessity of time since the shrinking sizes of component on-chip with advance in IC technology are making it BIST artistries are being rapidly developed and ...
