This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.
Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

Fall 2013
In underlay Cognitive Radio (CR) systems, secondary users may transmit while primary transmissions take place. However, the interference aggregates on the primary system, and performance degradation will occur. Thus, quantifying and modeling of the aggregate interference is important in...

Fall 2013
Cognitive radio is one of the most promising technologies to address the spectrum scarcity problem. Cognitive radio requires spectrum sensing, which is used by unlicensed users to opportunistically access the licensed spectrum. Spectrum sensing using energy detection offers low-cost and...

Fall 2019
Fifth generation (5G) wireless networks must handle massive data rates given the recent and future demand growth. A solution is the use of millimeter wave (mmW) bands (20-100 GHz) which can leverage massive bandwidths (up to 5 GHz). However, mmW signals experience high path loss,...

Analysis of Non-Coherent Detectors for Opportunistic Spectrum Access in Broadband Wireless Networks
DownloadSpring 2016
The exponential growth in the number of wireless broadband service users demands an enormous increase in the available communication bandwidth, which inherently translates into an increased demand for the radio frequency spectrum. Opportunistically accessing the unused portions of the spectrum...

Fall 2015
Although underlay networks mitigate the dual problems of spectrum congestion and spectrum under-utilization, the bi-directional (primary-to-secondary and secondary-to-primary) interference issues must be addressed to improve their reliability, coverage and capacity. To address these problems,...

Fall 2012
In this dissertation we present new methods for designing efficient Raptor codes in finite and practical block lengths. First we propose an extension of Raptor codes which keeps all the desirable properties, including the linear complexity of encoding and decoding per information bit, and...

Enhancing Backscatter Communication Networks: Optimization and Integration with Emerging Technologies
DownloadFall 2024
Future wireless networks require low cost, high spectral efficiency, and high energy efficiency. To achieve these goals, backscatter communication (BackComm) networks rely on passive reflective backscatter devices (tags). However, passive transmission causes low data rates and ranges. To address...

Fall 2017
Weighted sum-rate and common-rate optimization problems in wireless networks can be represented as the general forms of $\max\limits{}~ \sum{i=1}^N ai\log2(1+\gamma{i})$ and $\max~ \min\limits{i} (\gamma{i})$, respectively, where $\gammai$ represents the signal to noise ratio (SNR) of user...

Spring 2014
Bit/symbol error rate and outage probability are common performance metrics used to quantify the reliability of wireless communication systems. Error rates for a broad class of digital modulation schemes and outage probability are expressed as integrals, which often do not have closed-form...

Fall 2012
In this thesis, the problem of transmitting data in the form of multicast and broadcast traffic has been studied. The traffic can be from a real-time appli- cation which has a short block length or it can be a general broadcast traffic in an ad-hoc network. The goal is to reduce the total number...
