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.

    analysis of single-cell multi-user massive MIMO downlink. Perfect channel state information (CSI) is assumed at the BS and maximum ratio transmission (MRT) precoding scheme is adopted. We first investigate the distribution of the interference power and derive its probability density function (pdf) by

    central limit theory. After that, analytical results on the outage probability and the sum-rate are derived. Different to existing work using the law of large numbers to derive the asymptotic deterministic signal-to-interference-plus-noise-ratio (SINR), the randomness of the interference in the SINR is

    kept intact in our work, which allows the derivation of the outage probability. We further extend to networks with per-antenna power constraint. A modified MRT precoding scheme is proposed and the performance of the modified scheme is analyzed. Our work show that the modified MRT precoding can achieve
