  1. EELE 5490, Fall, 2009Wireless Communications Ali S. Afana Department of Electrical Engineering Class 1 Sep. 30th, 2009

  2. Outline • Instructor information • Motivation to study wireless communications and networks • Course descriptions and textbooks • What you will study from this course • Objectives • Coverage and schedule • Homework, projects, and exams • Other policies • Reasons to be my students

  3. Instructor Information • Office location: B262 • Email: aliafana@iugaza.edu • Phone: 2809 • Course website: http://www.iugaza.edu/aliafana • Research interests: Cognitive Radio Intelligent Wireless Communications

  4. Motivations • Recent Development • Cellular system: 3G, 4G, video, game, • WIFI everywhere • WIMAX, • UWB, no cables • Bluetooth, small devices connections • Job Market • Probably one of most easy and high paid majors recently • Intel changes to wireless, Micron will follow? Cypress • Research Potential • multiuser communication & Cognitive radio are still an open issues.

  5. Course Descriptions • What is the wireless communication system? • What are the wireless channels? • What are the theorems? • What are the major components and techniques? • How is the information transmitted? • What are the current industrial standards? • Can I find a job by studying this course? • Can I find research topics?

  6. Textbook and Software • Require textbook: Wireless Communications: Principles and Practice, 2nd Edition, Theodore S. Rappaport, Prentice Hall, 2001. • Require Software: MATLAB; • Recommended readings • Digital communications: J. Proakis, Digital Communications • Random process: G.R. Grimmett and D.R. Stirzaker, Probability and Random Processes • Estimation and detection: H.V. Poor, An introduction to Signal Detection and Estimation • Information theory: T. M. Cover and J. A. Thomas, Elements of Information Theory • Error correct coding: P.Sweeney, Error Control Coding • Computer Networks: A. S. Tanenbaum, Computer Networks

  7. Schedule • Cellular concept and network concept - Chapter 2 • Wireless Channel • Large scale loss: chapter 3 • Small scale loss, Fading: chapter 4 • Wireless communications technique • Modulation, chapter 5 • Equalization, diversity and channel coding, chapter 6 • Wireless Networks and Standards • chapter 8,9,10

  8. Homework, Project, and Exam • Homework • 3~4 questions per week • Projects: • Wireless Channel Simulation: simple MATLAB programs • Term presentation: • For research on xxx, what is the state-of-art • Exams • Votes for the percentages for homework, projects, and exams • Participations • Attendance and Feedback

  9. Teaching Styles • Slides plus black board • Slides can convey more information in an organized way • Blackboard is better for equations and prevents you from not coming. • A lesson from last semester: math • Course Website • Print handouts with 3 slides per page before you come • Homework assignment and solutions • Project descriptions and preliminary codes • Feedback • Too fast, too slow, small class advantages. • Presentation, English, …

  10. Reasons to be my students • Wireless Communication and Networking have great market • Usually highly paid and have potential to retire overnight • Highly interdisciplinary • Do not need to find research topics which are the most difficult part. • Research Assistant, Stipend • Free trips to conferences in Alaska, Hawaii, Europe, Asia… • A kind of nice (at least looks like) • Work with hope and happiness • Graduate fast
