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 ...
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 ...
Intelligent Systems Applications For Improving Power Systems Security
(2011-01-25)
Electric power systems are among the most complex man made systems on the world. Most of the time, they operate under quasi-steady state. With the ever increasing load demand and the advent of the deregulated power market ...
Analysis And Development Of Voltage Stability Assessment Methods
(2011-07-08)
Voltage stability is the ability of the power system to maintain steady acceptable voltages at all the buses in a system under normal operating conditions and after being subjected to a disturbance. The increased consumption ...
