1. ECE 390 Introductory Comments W. Grover ECE 390 Introduction to Communication Systems Welcome Class !

2. ECE 390 Introductory Comments W. Grover Who am I ? Wayne D. Grover 10 years BNR R&D (now Nortel Networks) involved in start-up of TRLabs consortium, ~1987 B.Sc. - Carleton U, Ottawa M.Sc. - U. Essex, U.K. Ph.D. - U. Alberta (‘89) - “Self-healing Networks” research and management roles at TRLabs since inception 1992 on Faculty U. of Alberta (ECE) 1995 Full Professor 2002 IEEE Fellow >100 papers, ~26 Patents Instructor web site: http://www.ece.ualberta.ca/~grover

3. ECE 390 Introductory Comments W. Grover ECE 390 : Educational Objective Graduates of ECE 390 will have a basic preparation in analog and digital communications. They will have basic knowledge and analysis skills applying to AM, FM, and digital communications. This prepares them to: –Take EE 488: performance of these systems in the presence of noise. This can be a path leading to graduate studies in Wireless Communications. –Function as computer engineers and system designers: –Prepare for careers in Telecommunications Industry

4. ECE 390 Introductory Comments W. Grover ECE 390 : “Classical” Careers in Telecom ? Not a “sure thing” like it used to be: jobs The Telecom “Boom” of ~1997-2001 created ~350,000 High Tech Jobs ? ? The “Bust” of ~2002-03 Wiped Out ~500,000 Jobs !!

5. ECE 390 Introductory Comments W. Grover ECE 390 : Careers in ECE and CompE ! On the other almost every computer or other electronic system nowadays involves communications technology and theory My car has a remote keyless entry Your keyboard may be wireless My printer has an InfraRed port Soon my ‘fridge will have an IP address ! There’s a LAN in your family car. And on the power lines in my house. I can play radio channels on my computer All images, sounds, movies are digital The I/O channel to a hard drive uses line coding and adaptive equalization... etc. etc. etc.

6. ECE 390 Introductory Comments W. Grover The message is …. System Designers, Computer Engineers, Electronics Designers (not just “Communication engineers”) all need a grounding in Communication Systems. This is probably the best real reason to take ECE 390 (and the reason it is now a “core course” for ECE degrees.)

7. ECE 390 Introductory Comments W. Grover But isn’t AM and FM pretty “old stuff ” ….? Digital is hot (and elegant !) But why FM and AM ? Aren’t they really old and only for our radios? Not really... Today we use AM and FM (PM) to carry digital signals. AM is also the basis of all digital “lightwave” transmission today and FDM is the basis of “DWDM” optical networking FM (PM) is the basis of many other high performance communication systems, including when the payload is digital. And remember…..Everything is actually ANALOG ANALOG & “Linear” = High performance !

8. ECE 390 Introductory Comments W. Grover Relationship to Other Courses EE 488 Communication in Noise EE 486 Optical Fiber Communication EE 489 Telecom. Systems Engineering and at the Grad Level: Digital Communication systems Data & Computer Networks Survivable Transport Network Design Multi-Media Systems

9. ECE 390 Introductory Comments W. Grover Cheating Don’t ! It matters ! I care and you should care too. There is a crack-down on at U of A It is against the oath you will swear when you get your Iron Ring If you know of cheating you are obliged to advise me Don’t put a red light on your career (My apologies to all those of you that wouldn’t even think of it…)
