On MMSE Approximations of Stationary Time Series
(University of Waterloo, 2014-01-20)In a large number of applications arising in various fields of study, time series are approximated using linear MMSE estimates. Such approximations include finite order moving average and autoregressive approximations as ... -
On Non-Binary Constellations for Channel Encoded Physical Layer Network Coding
(University of Waterloo, 2012-04-23)This thesis investigates channel-coded physical layer network coding, in which the relay directly transforms the noisy superimposed channel-coded packets received from the two end nodes, to the network-coded combination ... -
On Nonlinear Time-Invariant Behavioural Models of Power Transistors Used in the Computer-Aided Design of Power Amplifiers
(University of Waterloo, 2023-06-01)The Radio Frequency (RF) Power Amplifier (PA) is the main consumer of power in a wireless transmitter. Energy efficient PA design aided with circuit simulation tools requires accurate nonlinear models of the power transistors ... -
On Occupancy Based Randomized Load Balancing for Large Systems with General Distributions
(University of Waterloo, 2019-11-13)Multi-server architectures are ubiquitous in today's information infrastructure whether for supporting cloud services, web servers, or for distributed storage. The performance of multi-server systems is highly dependent ... -
On Optimal Online Policies in Energy Harvesting Communication Systems: Effects of Quality of Service and Battery Requirements
(University of Waterloo, 2016-04-27)We study the problem of finding optimal transmission policies in a point-to-point energy harvesting communication system with continuous energy arrivals in causal setting. In particular, we investigate bounds on the long-term ... -
On Optimum Conventional Quantization for Source Coding with Side Information at the Decoder
(University of Waterloo, 2007-09-26)In many scenarios, side information naturally exists in point-to-point communications. Although side information can be present in the encoder and/or decoder and thus yield several cases, the most important case that worths ... -
On Parallel Computation of Large Smooth-Degree Isogeny
(University of Waterloo, 2023-08-04)The computation of large smooth-degree isogenies is considered to be the most time-consuming task in isogeny-based cryptosystems and, to this end, recently several proposals have been made to speed it up. For implementation ... -
On Periodic Correlation of Binary Sequences
(University of Waterloo, 2007-01-04)A (periodic) correlation function is an important measure to evaluate the effectiveness of pseudorandom sequences. In practice, the sequences are required to have the impulse-like autocorrelation function. Also, crosscorrelation ... -
On Software Implementation of High Performance GHASH Algorithms
(University of Waterloo, 2012-10-23)There have been several modes of operations available for symmetric key block ciphers, among which Galois Counter Mode (GCM) of operation is a standard. GCM mode of operation provides confidentiality with the help of ... -
On Spectral Properties of the Grounded Laplacian Matrix
(University of Waterloo, 2014-08-19)Linear consensus and opinion dynamics in networks that contain stubborn agents are studied in this thesis. Previous works have shown that the convergence rate of such dynam- ics is given by the smallest eigenvalue of the ... -
On Techno-economic Evaluation of Wind-based DG
(University of Waterloo, 2010-01-22)The growing interest in small-scale electricity generation located near customers, known as Distributed Generation (DG), is driven primarily by emerging technologies, environmental regulations and concerns, electricity ... -
On the Asymptotic Number of Active Links in a Random Network
(University of Waterloo, 2012-09-01)A network of n transmitters and n receivers is considered. We assume that transmitter i aims to send data to its designated destination, receiver i. Communications occur in a single-hop fashion and destination nodes are ... -
On the Complexity of the Circuit Obfuscation Problem for Split Manufacturing
(University of Waterloo, 2014-04-22)Recent work in the area of computer hardware security introduced a number of interesting computational problems in the context of directed acyclic graphs (DAGs). In this thesis, we pick one of these problems, circuit ... -
On the Computation of Multi-Scalar Multiplication for Pairing-Based zkSNARKs
(University of Waterloo, 2023-07-21)Multi-scalar multiplication refers to the operation of computing multiple scalar multiplications in an elliptic curve group and then adding them together. It is an essential operation for proof generation and verification ... -
On the Design and Testing of Authorization Systems
(University of Waterloo, 2013-08-02)Authorization deals with the specification and management of accesses principals have to resources. In the design of an authorization system, sometimes we just implement the accessenforcement without having a precise semantics ... -
