Designing Solutions to Some of the Issues in Ubiquitous Networks
The inception of ubiquitous computing goes back to late eighties, when the Research at the Xerox Palo Alto Research (PARC) started designing ubiquitous environment under the guidance of Mark Weiser. Ubiquitous computing ... -
Development of High Throughput Intelligent Indoor Optical Wireless Communication Systems
The proliferation of mobile devices in indoor environments has led to insatiable demand for high-speed, high-bandwidth data connectivity. Optical wireless communication (OWC) is seen as a promising technology capable of ... -
Device Applications of Epitaxial III-Nitride Semiconductors
(2018-05-14)Through the history of mankind, novel materials have played a key role in techno- logical progress. As we approach the limits of scaling it becomes difficult to squeeze out any more extensions to Moore’s law by ... -
Device Structure And Material Exploration For Nanoscale Transistor
(2013-07-03)There is a compelling need to explore different material options as well as device structures to facilitate smooth transistor scaling for higher speed, higher density and lower power. The enormous potential of nanoelectronics, ... -
Differential Encoding for Real-Time Status Updates
We consider the problem of status updates of a physical process over an unreliable channel. In this setting, one may not be able to reliably transmit the current state at all times. Instead, one is interested in the ... -
Diffraction Tomographic Imaging With A Circular Array
(Indian Institute of Science, 2005-06-02)In the conventional diffraction tomography a linear array is used to receive forward scattered field. Then a standard algorithm like back propagation or Fourier domain interpolation is used for reconstruction of the object. ... -
Distributed Algorithms for Power Allocation Games on Gaussian Interference Channels
(2017-09-20)We consider a wireless communication system in which there are N transmitter-receiver pairs and each transmitter wants to communicate with its corresponding receiver. This is modelled as an interference channel. We propose ... -

Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ... -
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 ... -
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 ... -
DSP Techniques for Performance Enhancement of Digital Hearing Aid
(Indian Institute of Science, 2005-10-20)Hearing impairment is the number one chronic disability affecting people in the world. Many people have great difficulty in understanding speech with background noise. This is especially true for a large number of elderly ... -
Dynamic Dealy Compensation and Synchronisation Services for Continuous Media Streams
(Indian Institute of Science, 2005-09-14)Multimedia' nature of an application refers to the presence of several media streams in parallel. Whether it is receiving real-time data or retrieving stored data, there exists an end-to-end delay in data transfer from ... -
A Dynamic Security And Authentication System For Mobile Transactions : A Cognitive Agents Based Approach
(2011-01-25)In the world of high mobility, there is a growing need for people to communicate with each other and have timely access to information regardless of the location of the individuals or the information. This need is supported ... -
