Dr. Paul Cotae, Professor of Electrical and Computer Engineering has more than 25
years of experience in the communication field (research and education). He received a Dipl. Ing.
and a M.S. degrees in communication and electronic engineering in 1980 from the Technical
University of Iassy and a Ph.D. degree in telecommunications from “Politechnica” University of
Bucharest, Romania in 1991, and a Master in Applied Mathematics in 1998 from the University
of Colorado at Boulder. From 1994 to 1998 he spent four years at the University of Colorado at
Colorado Springs and the University of Colorado at Boulder as a Fulbright Scholar and Visiting
Associate Professor doing research and teaching in ECE department and APPM department. He
served also as a consultant to Navsys Corp., Colorado Springs, in 1997. From 2002 to 2008 he
was with the Department of Electrical and Computer engineering at the University of Texas at
San Antonio (UTSA). From 1984 to 2001, he was with the Department of Electrical Engineering,
Technical University of Iassy, where he conducted research and teaching in the area of digital
communications as a Full Professor at the same department. Since 2008, he has been with the
University of the District of Columbia as a Professor of Electrical Engineering. His current research interests
include multiple access, modulation and coding, mobile communications, and digital
communication systems. He has authored or coauthored more than 150 papers in these areas and
four books. Dr. Cotae serves as an Associate Editor for IEEE Communication Letters, EURASIP
Journal on Signal Processing, Elsevier International Journal of Computers and Electrical
Engineering (JCEE), and he has been on the Technical Program Committee and Session chair of
the IEEE Conferences GLOBECOM (2003-2011), VTC Spring 2005, 2006 and ICC 2005-2011.
He is a Senior Member of IEEE, member of ASEE, member of HKN (Eta Kappa Nu) and SIAM.
He is cited in Who’s Who in American Education, Who’s Who in America, and in Who’s Who in
the World. He has been nominated two times for the best teacher award (2005 and 2006) in the
College of Engineering at UTSA. He is the IEEE Vice Chair Washington Section and IEEE ComSoc chair Whasington
DC Section. He is Faculty Fellow for the ONR-ASEE Summer Faculty Research Program 2009-2018.

The malicious of quality of services attacks become one of the most serious security threats to the Internet. In this paper we focused on the detection of a low and slow rate attacks in Distributed Denial of Service (DDoS). In this kind of attack, a malicious attacker generates low rate packet and an attacker is congestions the TCP, so the network bandwidth is affected and degrades the quality of service. After a user enters in the retransmission timeout (RTO) phase, attackers synchronize with the RTO period and they can overcontrol the legitimate users. In this paper, we focus on the detection of (DDoS) attacks in spectral domain. We study our data using MATLAB and statistical methods. We used periodogram to find the malicious. We tested, analyzed and simulated different types of flows in a computer network by using MATLAB. Also, we use Fisher statistical methods for detection of the DDoS attacks components. The Fisher statistical methods used to study the data in multiple times series. Then, we test the data by using Fisher test to find an attacker that is hiding in the process. We applied the MATLAB toolboxes to study the data. We used to apply most communications and signal processing toolboxes to notice differences in the time domain and spectral domain. The paper has joined different engineering areas and levels to enhance students’ abilities. Student ambitions are crucial of excellent researcher and they are enhanced the technical backgrounds and research skills for students in Cybersecurity.
