Change in HW # 7

In HW # 7, problem # 1 was a repeat of the last problem of HW # 6, so you don't have to re-do it. I posted an updated version online and it only has 4 problems.

Change in HW # 7 deadline

HW # 7 will be due a week later, on Tuesday, October 23.

Change in HW # 6

In HW # 6, part (f) of problem # 3 has been removed. I posted an updated version online.

Slides for lecture 3

There were a couple of comments and suggestions brought up to me during last week and to try to address them I have posted some slides to use during the lecture tomorrow. I will be posting such slides for future lectures as well. The ones for tomorrow are here.

Welcome ECE 459 students!

To get started with the course, you can start reading carefully this website. You can find information about lecture, office hours, homework, exams, grading, etc. Please check this section for further announcements regularly.

Best wishes for the semester.

Lectures: TR, 9.30am-10.50am, 3081 Electrical & Computer Eng Bldg.

Lecture Attendance Policy: We invite relevant questions and comments during lectures. Address your questions and comments to the entire class; avoid disruptive behavior such as talking to neighbors, unless the instructor invites you to form discussion groups. Kindly turn off or mute cell phones, laptop computers, and other electronic devices during lectures.

Suggested (not required) textbook: Custom book for ECE459, ISBN: 978-1269807500 (available at IUB and TIS). It has only the chapters that we cover from the textbook: J. G. Proakis and M. Salehi, Fundamentals of Communication Systems, 2nd edition, Prentice-Hall, ISBN: 978-0133354850. You can use either one as a reference.
Others are at Grainger in reserve.
