Analysis Of Multichannel And Multimodal Biomedical Signals Using Recurrence Plot Based Techniques
(2015-12-01)
For most of the naturally occurring signals, especially biomedical signals, the underlying physical process generating the signal is often not fully known, making it difficult to obtain a parametric model. Therefore, signal ...
Space-Time Block Codes With Low Sphere-Decoding Complexity
(2017-05-04)
One of the most popular ways to exploit the advantages of a multiple-input multiple-output (MIMO) system is using space time block coding. A space time block code (STBC) is a finite set of complex matrices whose entries ...
Nonstationary Techniques For Signal Enhancement With Applications To Speech, ECG, And Nonuniformly-Sampled Signals
(2015-07-22)
For time-varying signals such as speech and audio, short-time analysis becomes necessary to compute specific signal attributes and to keep track of their evolution. The standard technique is the short-time Fourier transform ...
Design And Development Of Customer Context-Aware Mobile Commerce Services
(2016-12-22)
The technological advances in wireless networks, smart phones, social networks, embedded sensor technologies and the wide spread of mobile devices have exposed customers to number of services. With these advanced technological ...
Design And Analysis Of Integrated Optic Resonators For Biosensing Applications
(2016-09-15)
In this thesis, we have designed and optimized strip waveguide based micro-ring and micro-ring and micro-racetrack resonators for biosensing applications. Silicon-On-Insulator (SOI) platform which offers several advantages ...
High-k Dielectrics For Metal-Insulator-Metal Capacitors
(2016-11-23)
Metal-insulator-metal (MIM) capacitors are used for analog, RF, and DRAM applications in ICs. The International Technology Roadmap for Semiconductors (ITRS) specifies continuing increase in capacitance density (> 7 fF/ ...
The Combined Effect Of Reduced Feedback, Frequency-Domain Scheduling, And Multiple Antenna Techniques On The Performance Of LTE
(2014-11-21)
Frequency-domain scheduling, multiple antenna techniques, and rate adaptation enable next generation orthogonal frequency division multiple access (OFDMA) cellular systems such as Long Term Evolution (LTE) to achieve ...
Who Spoke What And Where? A Latent Variable Framework For Acoustic Scene Analysis
(2016-09-15)
Speech is by far the most natural form of communication between human beings. It is intuitive, expressive and contains information at several cognitive levels. We as humans, are perceptive to several of these cognitive ...
Bitrate Reduction Techniques for Low-Complexity Surveillance Video Coding
(2017-09-26)
High resolution surveillance video cameras are invaluable resources for effective crime prevention and forensic investigations. However, increasing communication bandwidth requirements of high definition surveillance videos ...
Codes With Locality For Distributed Data Storage
(2017-07-26)
This thesis deals with the problem of code design in the setting of distributed storage systems consisting of multiple storage nodes, storing many different data les. A primary goal in such systems is the efficient repair ...
