Multi-Antenna Communication Receivers Using Metaheuristics and Machine Learning Algorithms
(2018-04-23)In this thesis, our focus is on low-complexity, high-performance detection algorithms for multi-antenna communication receivers. A key contribution in this thesis is the demonstration that efficient algorithms from ... -
Multi-connectivity for Urllc and Coexistence with Embb in Time-varying and Fading Channels
Ultra-reliable and low latency communications (URLLC) is a novel use case of 5G. It has challenging requirements like such as low block error rates (BLERs) and stringent latency targets. Multi-connectivity, in which multiple ... -
Multistage pattern recognition schemes for automatic... ... verification
This thesis presents studies on the application of multistage pattern?recognition schemes in automatic speaker identification and verification systems for large populations. The success of speaker?recognition schemes in ... -
Nature-inspired Algorithms for Automated Deployment of Outdoor IoT Networks
A vast majority of the Internet of Things (IoT) devices will be connected in a topology where the edge-devices push data to a local gateway, which forwards the data to a cloud for further processing. In sizeable outdoor ... -
Network Coding for Wirless Relaying and Wireline Networks
(2017-12-10)Network coding has emerged as an attractive alternative to routing because of the through put improvement it provides by reducing the number of channel uses. In a wireless scenario, in addition, further improvement can be ... -
Neuronal Dissimilarity Indices that Predict Oddball Detection in Behaviour
(2017-09-23)Our vision is as yet unsurpassed by machines because of the sophisticated representations of objects in our brains. This representation is vastly different from a pixel-based representation used in machine storages. It is ... -
New clock synchronization techniques for digital telecommunication networks
Slip rate minimization in digital telecommunication networks is now an area of considerable importance. As the slip rate depends directly on the network clock stability, a number of clock synchronization techniques have ... -
NoC Design & Optimization of Multicore Media Processors
(2018-03-22)Network on Chips[1][2][3][4] are critical elements of modern System on Chip(SoC) as well as Chip Multiprocessor(CMP)designs. Network on Chips (NoCs) help manage high complexity of designing large chips by decoupling ... -
Non linear vibrations of stretched strings
The viscosity of pure Freon-12 and Freon-22 vapours and their mixtures has been determined by an oscillating disc viscometer at room temperature and pressure. The results agree well with the published data for the pure ... -
Non linear vibrations of stretched strings
The results obtained in this chapter can be summarized as follows. It is not possible to induce purely transverse oscillations since longitudinal and transverse oscillations are coupled together. However, if the order of ... -
Non-Invasive Microwave Hyperthermia
(Indian Institute of Science, 2006-01-18)Presented in this thesis are the following theoretical investigations carried out on the non-invasive microwave hyperthermia of malignant tumours in the human body: Fundamental concepts of electromagnetic wave ... -
Non-uniform sample based speech analysis and coding
The utility of non?uniform sample?based analysis and reconstruction of speech signals is explored. Instead of a perfect reconstruction criterion, properties of speech perception are exploited to select non?uniform samples ... -
Nonexponential decay of sound in rooms
(i) The above analysis of decay of sound in rectangular rooms under various boundary conditions shows that the overall decay is in general non?exponential because the normal modes corresponding to different angles of ... -
Nonlinear D/A and A/D converters some new techniques and applications
The development of new techniques for realizing nonlinear D/A and A/D converters, followed by their hardware implementation and/or computer simulation, has been described in this thesis. Also covered in the thesis are many ... -
Nonlinear Optical Enhancement Studies in Silicon-based Resonant Metasurfaces
Metasurfaces are two dimensional arrangements of building blocks called meta-atoms which have been found to be useful to manipulate amplitude, phase, polarization of light at the nanoscale. Using these properties, functional ... -
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 ... -
