Sub-optimal and robust downlink beamforming in wireless networks with imperfect channel state information
(University of Missouri--Columbia, 2021)
). The fourth generation (4G) wireless technologies introduced a with promising technique known as multiple-input-multiple-output (MIMO) paradigm. The MIMO offers spatial diversity of multiple signals between the source and the destination which can ensure high...
Localization in challenging environment using geometric and machine learning techniques
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The establishment of robust sensor network applications requires accurate and non complex positioning techniques using a full or partial set of ...
Bayesian approach for the spectrum sensing mimo-cognitive radio network with presence of the uncertainty
(University of Missouri--Columbia, 2021)
A cognitive radio technique has the ability to learn. This system not only can observe the surrounding environment, adapt to environmental conditions, but also efficiently use the radio spectrum. This technique allows the ...
Breast cancer imaging and detection using microwave technique
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Worldwide, breast cancer continues to be the top cause of death among women and the second-leading cause of cancer death after lung cancer. ...
Antenna designs and imaging algorithm for radar-based microwave breast cancer detection
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work, the design of ultra-wideband antennas and an algorithm for artifact removal and image reconstruction beamforming for microwave breast ...
