Distributed Wireless Networks : Link Scheduling And Application Delay Modelling
(2013-05-23)
We address several problems that arise in a multihop wireless mesh network. First, we study the problem of joint congestion control, routing and MAC layer scheduling. We formulate the problem as an aggregate utility ...
Design & Implementation Of Low Power Sigma Delta ADCs For Wide Band Applications
(2013-06-13)
This thesis focuses on the design and implementation of low power Σ∆ ADCs in 130 nanometer CMOS technology. The design issues in the implementation of a third order ADC with a multi-bit and single bit quantizer are discussed. ...
Flexible Constraint Length Viterbi Decoders On Large Wire-area Interconnection Topologies
(2010-12-30)
To achieve the goal of efficient ”anytime, anywhere” communication, it is essential to develop mobile devices which can efficiently support multiple wireless communication standards. Also, in order to efficiently accommodate ...
Investigations On Boundary Selection For Switching Frequency Variation Control Of Current Error Space Phasor Based Hysteresis Controllers For Inverter Fed IM Drives
(2011-08-04)
Current-Controlled Pulse Width Modulated (CC-PWM) Voltage Source Inverters (VSIs) are extensively employed in high performance drives (HPD) because of the considerable advantages offered by them, such as, excellent dynamic ...
Multilevel Inverter Topologies With Reduced Power Circuit Complexity For Medium Voltage High Power Induction Motor Drives By Cascading Conventional Two-Level And Three-Level Inveters
(2011-02-10)
Multilevel inverters have advantages over two-level inverters such as reduced THD, ability to operate at low switching frequencies, reduced switching losses etc. Moreover, higher voltage levels can be handled with devices ...
Topics On Security In Sensor Networks And Energy Consumption In IEEE 802.11 WLANs
(2011-05-19)
Our work focuses on wireless networks in general, but deals specifically with security in wireless sensor networks and energy consumption in IEEE 802.11 infrastructure WLANs.
In the first part of our work, we focus on ...
Analytical Modeling Of Quantum Thershold Voltage For Short Channel Multi Gate Silicon Nanowire Transistors
(2010-12-29)
Silicon nanowire based multiple gate metal oxide field effect transistors(MG-MOSFET) appear as replacements for conventional bulk transistors in post 45nm technology nodes. In such transistors the short channel effect(SCE) ...
