Nonlinear Compensation in Optical Communications Systems using the Nonlinear Fourier Transform
(North Dakota State University, 2017)Nonlinear effects in optical fibers impose a capacity limit for optical communication systems. In this dissertation, the nonlinear Fourier transform (NFT) is investigated as a method to mitigate and compensate for those ... -
Metamaterial-Inspired Reconfigurable Series-Fed Arrays
(North Dakota State University, 2014)One of the biggest challenges in modern day wireless communication systems is to attain agility and provide more degrees of freedom in parameters such as frequency, radiation pattern and polarization. Existing phased array ... -
Efficient Message Dissemination Framework for Diverse Wireless Networks
(North Dakota State University, 2014)Wireless networks exhibit diversity, ranging from mostly disconnected delay tolerant networks and partially connected mobile ad hoc networks, to mostly connected cellular networks. Besides having useful applications, ... -
Fault Tolerant and Adaptive Systems with Focus on Networks-On-Chips
(North Dakota State University, 2014)The first step in design of reliable systems is the ability to evaluate the reliability of the system. This is an important step in the process of designing reliable systems because design techniques that proactively improve ... -
On the Secrecy Capacity of Fading Gaussian Wire-Tap Channel
(North Dakota State University, 2014)We consider the so called “wire-tap channel”, where a transmitter sends secret information to its receiver in the presence of an eavesdropping receiver with similar signal processing capability as the desired receiver. It ... -
Implementation of Fourier Repetitive Control in Labview
(North Dakota State University, 2014)This thesis presents position control as well as current (torque) control of a DC servo motor with a periodic input. Position control is achieved by using Fourier repetitive control scheme. Simulation on position control ... -
Performance Enhancement of Pipeline ADCs
(North Dakota State University, 2014)The pipeline ADC is mainstream architecture in wireless communication and digital consumer products because of its speed, resolution, dynamic performance, and power consumption. However, there are three areas of concern ... -
Network Convergence in Multicarrier Hybrid Cellular Network
(North Dakota State University, 2014)In a multicarrier communication system with known channel state information at transmitter (CSIT), it is well-known that the water-filling power allocation scheme is optimal in achieving the Shannon capacity. However, in ... -
Detection and Quantification of Rare Analytes in Biological Samples using Dielectrophoretic Spectroscopy
(North Dakota State University, 2017)Novel techniques for Dielectrophoresis (DEP) crossover frequency calculation, positive dielectrophoretic spectroscopy and negative dielectrophoretic spectroscopy are proposed in this dissertation. A novel automated immunoassay ... -
Using Formal Methods to Validate the Usage, Protocols, and Feasibility in Large Scale Computing Systems
(North Dakota State University, 2014)A paradigm shift has occurred in the Information and Communication Technology sector. The main obstacle to relegate complex and sensitive tasks is not the inadequate speed and unsatisfactory computing power of the existing ... -
Zeroth Order Resonator (ZOR) Based RFID Antenna Design
(North Dakota State University, 2014)Meander-line and multi-layer antennas have been used extensively to design compact UHF radio frequency identification (RFID) tags; however the overall size reduction of meander-line antennas is limited by the amount of ... -
