Proakis, Digital Communications

Barry, Lee, Messerschmitt, Digital Communication: Third Edition

Biglieri, Benedetto, Principles of Digital Transmission: With Wireless Applications.

Fischer, Precoding and Signal Shaping for Digital Transmission

Haykin, Moher, Modern Wireless Communications

 Course Objectives:  

This course supplements EECE 576 Statistical Communication Theory.

The course objective is to let the student obtain
1) the analytical skills required to analyze and design basic digital communication systems in the physical layer, and
2) the fundamental understanding of communication systems that may help them study advanced topics and consequently make significant contributions to the theory and the practice of digital communications.

Contact the instructor for questions about prerequisites.

 Course Requirements:

1. Midterm exam (TBA, Lec. 1-14)  20 %
2. Final exam (TBA, Lec. 1-29)  30 %
3. Homework and Quiz 40 %
4. Participation 10 %
100 %
In each exam, a student is allowed to bring an A4-size crib sheet written on both sides.  
Course participation is graded subjectively by the instructor based on the class attendances, active participation in discussions, office hour visiting, voluntary projects, etc.
Final grade will be based on total score.

 Grading Policies for Homework 

  1. Homework will be assigned approximately every week.

  2. It will not be collected. However, the quizzes on the due dates will include the homework.

  3. A quiz will be taken every class meeting to check whether a student have studied the course material to be covered in the corresponding class meeting.

  4. Re-grade requests must be filed in writing within one week after the graded homework has been returned to students.

  5. Each sub-problem will be graded according to the following scale: 100%, 60%, 20%, and 0%. 

 Grading Policies for Exam 

  1. Students may take exams earlier than the original schedule if he/she requests at least one week earlier. 

  2. Excused class absence on an exam day may lead to a make-up exam for the absentee.

  3. Re-grade requests must be filed in writing within one week after the graded exam has been returned to students.  

  4. Each sub-problem will be graded according to the following scale: 100%, 60%, 20%, and 0%. 

 Policy on Academic Dishonesty

If the instructor suspects academic dishonesty, the instructor will notify the student(s) and follow the procedure to report to the Graduate School without any exception. Students have the responsibility to be knowledgeable about the consequences of dishonesty.
