Course Description
The major goal of Introduction to Communication Systems (or, as it was called before, Principles of Communication Engineering I) is to teach students about the basic principles underlying the operation and design of a communication system. It is a core course for students in communications. The course will cover the following topics:
- Random processes
- Basics of modulation
- Continuous-wave modulation
- Pulse modulation
- Baseband digital transmission
- Signal-space analysis
These topics follow roughly the first five chapter of the class' textbook (Haykin).
We expect a student who finishes the course to be able to understand the basic operating principles of current communication systems. 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:
- Probability
- Basics in real analysis
- Basics in complex numbers
- Basics in linear algebra

Teaching Assistant
In case you would like to discuss some questions in Chinese, you may contact the TA of this class:
- Lee Ting-Hsuan
e-mail:
Office: Engineering Building IV, Lab 716A (ED716A)
Phone: 03-571 21 21 ext. 54630
To make our and your life easier, let's agree on the following rule: You may contact or visit the TA at any time also outside of office hours. However, if you haven't made an appointment in advance, she has the right to tell you that she hasn't got time right at that moment.
Time and Place
The course is scheduled for 4 hours per week:
- Tuesday, 13:20–15:10 (EF), Engineering Building IV, Room 303 (ED303)
- Thursday, 13:20–15:10 (EF), Engineering Building IV, Room 303 (ED303)
The course starts on Tuesday, 18 September 2012, and finishes on Thursday, 17 January 2013.
Office Hours
NCTU requests that every teacher offers two hours per week where students may come to ask questions. I will, of course, also do so:
- Tuesday, 15:30–17:30, Engineering Building IV, Office 727 (ED727)
However, we would like to encourage you to show up in the teacher's or teaching assistants' office at any time whenever you have questions about the class or related subjects. Moreover, we are always available during and after classes.
Textbook
The course will be based on
Additional recommended readings:
- Robert G. Gallager: “Principles of Digital Communication,” Cambridge University Press, 2008.
Further 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.
For certain topics there will be additional handouts during classes.
Exercises
Every week, an exercise will be distributed in class and also 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 distributed and made 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 one mid-term and one final exam. Both exams are going to last three hours and be open-book. Details about the covered material in the mid-term exam will be published in due time. The final exam will cover everything taught in class.
Grading
The grade will be an average of
- the homework and class participation (15%),
- the mid-term exam (35%), and
- the final exam (50%).
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. Moreover, I will try to reward students who participate actively in class.
This course is worth 3 credits.
Special Remarks
The lecture will be held in English.
