Nonlinear Processing Of EEG and HRV Signals For The Study Of Physiological And Pathological States
(2013-04-26)Physiological signals, electroencephalogram (EEG) and heart rate variability (HRV), are generated by complex self-regulating systems. These signals are extremely inhomogeneous and nonstationary, and fluctuate in an irregular ... -
Nonlinear propagation of surface acoustic waves
Some problems relating to the nonlinear propagation of surface acoustic waves on an isotropic homogeneous medium are studied in this thesis using a perturbation approach. The propagation of finite amplitude surface acoustic ... -

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 ... -
Novel instrumentation and communication system for GMRT�
Radio telescopes are indispensable tools for frontline research in astronomy and astrophysics. In all radio telescopes, the control and monitor system provides the necessary coordination between the various building blocks ... -
Novel motion compensated prediction technique for video compression using adaptive vector quantization
In digital communication, compression is necessary for transmitting huge amounts of information over very narrow channels or for efficient storage of digital information. Visual information plays a key role in modern digital ... -
On Codes for Private Information Retrieval and Ceph Implementation of a High-Rate Regenerating Code
(2018-07-09)Error-control codes, which are being extensively used in communication systems, have found themselves very useful in data storage as well during the past decade. This thesis deals with two types of codes for data storage, ... -
On Design and Analysis of Energy Efficient Wireless Networks with QoS
(2018-06-13)We consider optimal power allocation policies for a single server, multiuser wireless communication system. The transmission channel may experience multipath fading. We obtain very efficient, low computational complexity ... -
On Linear Codes in Projective Spaces
The projective space $\mathbb{P}_q(n)$ of order $n$ over a finite field $\mathbb{F}_q$ is defined as the collection of all subspaces of the ambient space $\mathbb{F}_q^n$. The Grassmannian $\mathcal{G}_q(n, k)$ is the set ... -
On Media-Based Modulation for Wireless Communications
Traditionally, symbols chosen from complex modulation alphabets such as QAM and PSK are used to convey information bits, and complex fades introduced by the channel are viewed as detrimental effects that cause amplitude ... -
On Network Coding and Network-Error Correction
(2018-04-24)The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information flow networks. Network coding makes use of the fact that unlike physical commodities, ... -
On Orthogonal Time Frequency Space Modulation for Wireless Communications
Future wireless communication systems are envisioned to support diverse requirements that include high mobility application scenarios such as high-speed trains, and vehicle-to-vehicle and vehicle-toinfrastructure communications. ... -
On Reduced-State Optimal Scheduling for Decentralized Medium Access Control of Wireless Data Collection Networks
In the Internet of Things (IoT), devices such as sensors and actuators will almost invariably be connected to the Internet via wireless networks. The sensor and actuator devices in such systems will be resource challenged ... -
On Some Questions Involving Prefix Codes
Let A be a finite alphabet and A be the set of all finite sequences of the elements of A. A word is any member of A . A prefix code X is a set of words satisfying the prefix property, i.e., no word in the set is a prefix ... -
On Streaming Codes, Regenerating Codes and Locality-Aided Decoding
This thesis presents results relating to the application of error-correcting codes with different aims and in different settings; to achieve low-latency communication, to improve decoding performance and to enable the ... -
On The Best-m Feedback Scheme In OFDM Systems With Correlated Subchannels
(2017-07-07)Orthogonal frequency division multiplexing (OFDM) in next generation wireless systems provides high downlink data rates by employing frequency-domain scheduling and rate adaptation at the base station (BS). However, in ... -
On the dimension and exceptional subspaces of SSRS codes
A class of nonlinear cyclic error-correcting codes, known as Subspace Subcodes of Reed-Solomon (SSRS) codes, is studied in this thesis. An SSRS code is a subcode of a Reed-Solomon (RS) code consisting of RS codewords whose ... -
On The Fourier Transform Approach To Quantum Error Control
(2013-10-07)Quantum mechanics is the physics of the very small. Quantum computers are devices that utilize the power of quantum mechanics for their computational primitives. Associated to each quantum system is an abstract space known ... -
On the optimization of control memory and data paths in the design of microprogrammed computers and microprocessors
In a microprogrammed processor, the size of the control memory depends upon the microinstruction word length (width of the control memory). An optimal microinstruction format reduces the width and hence the size of the ... -
On the Sum-Rate Capacity of Gaussian X Channels
Interference caused by the reception of unintended signals at the receivers is a major source of performance bottleneck limiting the capacity of wireless communication systems. An interesting model to study the effect of ...
