A Polymorphic Finite Field Multiplier
(2013-07-03)
Cryptography algorithms like the Advanced Encryption Standard, Elliptic Curve Cryptography algorithms etc are designed using algebraic properties of finite fields. Thus performance of these algorithms depend on performance ...
Precoding for Interference Management in Wireless and Wireline Networks
(2018-02-27)
Multiple users compete for a common resource like bandwidth to communicate
data in interference networks. Existing approaches in dealing with interference
limit the rate of communication due to paucity of shared resources. ...
Design and Development of a Passive Infra-Red-Based Sensor Platform for Outdoor Deployment
(2018-04-23)
This thesis presents the development of a Sensor Tower Platform (STP) comprised of an array of Passive Infra-Red (PIR) sensors along with a classification algorithm that enables the STP to distinguish between human intrusion, ...
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 ...
Fast, Scalable, Contention-Based Algorithms for Multi-Node Selection in OFDMA and Cooperative Wireless Systems
(2018-04-23)
Opportunistic selection algorithms have grown in importance as next generation wireless systems strive towards higher data rates and spectral efficiencies. For example, in orthogonal frequency division multiple access(OFDMA), ...
Analytical And Numerical Study Of Propagation In Optical Waveguides And Devices In Linear And Nonlinear Domains
(2010-07-23)
The objective of this thesis is to study of optical effects, arising in the form of non-uniform waveguide structure, complicated refractive index profiles or due to pulse propagation in dense wavelength division multiplexing ...
Low Decoding Complexity Space-Time Block Codes For Point To Point MIMO Systems And Relay Networks
(2010-07-12)
It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) ...
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)
In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ...
Providing QoS To Real-time And Data Applications In 3G Wireless Systems
(2010-07-29)
In this thesis we address the problem of providing end-to-end quality of service (QoS) to real-time and data connections in a third generation (3G) cellular network based on the Universal Mobile Telecommunication System ...
