Structure of the Course

The course consists of 28 lectures, 6 homework assignments, 1 project, and 2 exams.

This course is primarily a lecture course.   I cover all important material in lectures.  Since EEL 5544 is a  prerequisite, I assume some previous knowledge about probability theory and stochastic processes, and hence I will cover some material very quickly.  Thus, depending on what and how much you recall from earlier study, varying amounts of reading in introductory books on probability theory and stochastic processes (other than the course textbook) may be necessary; these readings are up to the student.  I will only give reading assignments from the course textbook.

Some problems in the exams will be similar to those in the homework.   As long as you work out the homework by yourself, you will be successful in the exams.   The problems in the exams are designed to prevent the students from memorizing the homework solutions without understanding the fundamental principles, concepts, and theories.   So, to prepare the exams, the first thing is to understand the material; then use the homework problems to test your understanding.

The class project is described here.

Class Project:

The class project will be done in a group of at most four members (that is, 1 or 2 or 3 or 4 members are allowed).   Each project requires a proposal and a final report.   The final report is expected to be in the format of a conference paper.    On March 20, the project proposal (up to 2 pages) is due.  On April 28, the final report (up to 10 pages) is due.   For details about the project, please read here.  On May 1, each project team needs to give a poster presentation.

Suggested topics for projects are listed here.
