Course Objectives

The major goal of Principles of Communication Engineering (I,II) is to teach students about the basic principles underlying the operation and design of a communication system. It is a core course in the Department of Communication Engineering. The course will follow approximately the following schedule:

• Passband Digital Transmission (Chapter 6)
• Spread Spectrum Modulation (Chapter 7)
• Multiuser Radio Communications (Chapter 8)
• Fundamental Limits in Information Theory (Chapter 9)
• Error-Control Coding (Chapter 10)

For more detail see the time table below.

We expect a student who finishes the course to be able to understand the basic operating principles of current communication systems or standards. Moreover, we sincerely hope that a student who learns the course material will be equipped with the ability to analyze and design a communication system.

Prerequisites

The following lectures/topics are recommended:

• Signals and Systems (preferably)
• Probability (preferably)
• Principles of Communication Engineering I (preferably)

Instructors

This course is taught in parallel by two teachers.

Prof. Su Yu Ted	Prof. Stefan M. Moser

Time and Place

The course is scheduled for 4 hours per week:

• Tuesday, 13:30-15:20, Engineering Building IV
  Room 203 (ED203) for the Chinese class
  Room 111 (ED111) for the English class
• Thursday, 13:30-15:20, Engineering Building IV
  Room 203 (ED203) for the Chinese class
  Room 111 (ED111) for the English class

The course starts on Tuesday, 19 February, and finishes on Thursday, 19 June.

Office Hours

NCTU requests that every teacher offers two hours per week where students may come to ask questions:

• Prof. Su: Tuesday, 15:30-17:30, Engineering Building IV, Office 803
• Prof. Moser: Tuesday, 15:30-17:30, Engineering Building IV, Office 727

However, we would like to encourage you to show up in the teacher's or teaching assistant's office at any time in case you have questions about the class or related subjects. Moreover, we are always available during and after classes.

Textbook

Simon Haykin: "Communication Systems," 4th ed., Wiley, 2001.

Further references and recommended readings:

• R. E. Ziemer and W. H. Tranter: "Principles of Communications," 5th ed., Wiley, 2002.
• John G. Proakis: "Digital Communications," 4th ed., McGraw-Hill, 2001.
• Thomas M. Cover and Joy A. Thomas: "Elements of Information Theory," second edition, Wiley, 2006.

For certain topics there will be additional handouts during classes.

Exercises

Every week, an exercise will be made available online for download. This exercise will consist of several problems that need to be solved at home and handed in during the class of the following week. A model solution will be available online afterwards.

We believe the exercises to be extremely important and crucial to the understanding of the course. They also serve as a preparation for the mid-term and final exams and we therefore highly recommend to solve them. To pass the course you need to hand in at least 10 exercises.

Exams

There will be three mid-term exams and one final exam. The mid-term exams are going to last one hour and be closed-book. The final exam will be three hours and open-book. Details about the covered material will be published in due time.

Grading

The grade will be an average of

• the homework (15%),
• the midterm exams (15% each), and
• the final exam (40%).

The grade of the homework will not be based on the correctness of the answers, but rather on the effort the student shows in trying to solve them. This course is worth 3 credits.

Special Remarks

The course is taught in parallel in two classes: one class is taught in Chinese, one class is taught in English. Note, however, that all exercises, handouts, and exams will be identical in both classes and written in English only.
