Process Variability-Aware Performance Modeling In 65 nm CMOS
(2011-02-25)
With the continued and successful scaling of CMOS, process, voltage, and temperature (PVT), variations are increasing with each technology generation. The process variability impacts all design goals like performance, ...
QoS Aware Quorumcasting Over Optical Burst Switched Networks
(2010-10-11)
Recently there is an emergence of many Internet applications such as multimedia, video conferencing, distributed interactive simulations (DIS), and high-performance scientific computations like Grid computing. These ...
Coplanar Capacitive Coupled Probe Fed Ultra-Wideband Microstrip Antennas
(2010-12-07)
Modern wireless communication systems call for ultra wideband operations to meet the continuous growth in the number of users of these systems. Since antenna is an integral part of any wireless communication system ...
Diversity-Multiplexing Gain Tradeoff Of Cooperative Multi-hop Networks
(2010-08-23)
We consider single-source single-sink (ss-ss) multi-hop relay networks, with slow-fading links and single-antenna half-duplex relay nodes. While two-hop cooperative relay networks have been studied in great detail in terms ...
Spectro-Temporal Features For Robust Automatic Speech Recognition
(2011-01-18)
The speech signal is inherently characterized by its variations in time, which get reflected as variations in frequency. The specto temporal changes are due to changes in vocaltract, intonation, co-articulation and successive ...
Belief Propagation Based Signal Detection In Large-MIMO And UWB Systems
(2011-02-03)
Large-dimensional communication systems are likely to play an important role in modern wireless communications, where dimensions can be in space, time, frequency and their combinations. Large dimensions can bring several ...
Diversity-Mutiplexing Tradeoff Of Asynchronous Cooperative Relay Networks And Diversity Embedded Coding Schemes
(2010-08-23)
This thesis consists of two parts addressing two different problems in fading channels.
The first part deals with asynchronous cooperative relay communication. The assumption of nodes in a cooperative communication relay ...
Guessing And Compression : A Large Deviations Approach
(2011-04-01)
The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ...
Summer-Less Dual Charge Pump Based PLL With Wide Lock Range Using Analog Frequency Detector
(2011-01-18)
Phase Locked Loop (PLL) is an integral component of clock generation circuits. A third order Charge Pump PLL (CPPLL) is most widely employed PLL architecture due to its zero steady state phase error. A monolithic implementation ...
A Workload Based Lookup Table For Minimal Power Operation Under Supply And Body Bias Control
(2011-01-25)
Dynamic Voltage Scaling (DVS) and Adaptive body bias (ABB) techniques respectively try to reduce the dynamic and static power components of an integrated circuit. Ideally, the two techniques can be combined to find the ...
