Lectures: TR, 9.30am-10.50am, 3013 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.
