Congratulations to Eyosias Yoseph Imana for successfully defending his dissertation on Friday, November 21.
Dr. Jeff Reed is featured in the CTIA Multimedia Library "Wonder of Wireless" campaign this week highlighting a speech he gave on the Net Neutrality Debate. Dr. Reed is the Willis G. Worcester Professor in the Electrical Engineering Department of Virginia Tech as well the founding director of Wireless @ VT. CTIA is is an international nonprofit membership organization that has represented the wireless communications industry since 1984. CTIA Super Mobility Week is the premier trade show event in the wireless industry. CTIA is also an active advocate for the wireless industry at all levels of government. We have embedded the videos for your convenience:
SaiDhiraj Amuru successfully passed his Preliminary Exam, Friday, November 7, 2014. The Preliminary Examination is taken near the end of Ph.D. course work and at least 9 months before the dissertation defense. This is an oral exam taken before the student’s advisory committee that determines the student’s ability to develop scholarly research. The student presents the results of his or her current research along with an outline of a proposed Ph.D. dissertation. SaiDhiraj's research and dissertation will investigate specific aspects of "intelligent-jamming":
"Spectrum supremacy is a vital part of security in the modern era. In the past 50 years a great deal of work has been devoted to designing defenses against RF-based electronic attacks (i.e., anti-jamming), but significantly less work has been devoted to the equally important task of designing effective strategies for preventing (i.e., jamming) wireless communication between malicious nodes within an area (e.g., in a secure private location). Owing to dynamic conditions in practical wireless environments, it is most likely not possible to obtain a priori information regarding the malicious nodes. Therefore, it is necessary for the jammers to have cognitive capabilities that provide the ability to learn the environment and prevent the malicious nodes from accessing the valuable spectrum. In this regard, we ask the following question in this research “Can an intelligent jammer learn and adapt to unknown environments in an electronic warfare-type scenario?” Fundamentally speaking, we explore whether the existing machine learning techniques in the open literature can be used to address such cognitive scenarios and if not, what are the missing pieces that will enable a jammer to achieve spectrum supremacy by denying an adversary (or malicious nodes) the ability to communicate."

Wireless @ Virginia Tech faculty members Dr. Allen MacKenzie (Associate Director) and Dr. Carl Dietrich (Associate Research Professor) will be teaching two classes in Spring 2015.
Dr. MacKenzie will be teaching a graduate level only course in Error Control Coding, ECE 5684. Error Control Coding is, of course, fundamental for building near-capacity-achieving wireless communication systems. The course will cover some of those near-capacity-achieving approaches, like Turbo Codes and LDPC codes. More information on this course is available on the ECE website at http://www.ece.vt.edu/graduate/courses/viewcourse.php?number=5684-260. Contact Dr. MacKenzie at mackenab at vt.edu for additional information.
Dr. Carl Dietrich will be teaching a senior level/graduate level course in Software and Cognitive Radio Design, ECE 4984. This project-oriented, hands-on course introduces software-defined radio (SDR) and cognitive radio (CR), technologies that are reshaping wireless communications. Students will prepare for employment or graduate study by working in teams to design, develop, present/demonstrate and document a system or component that meets user requirements and specifications. More information on this class is available here. You can contact Dr. Dietrich at cdietric at vt.edu.
