EE/Ma 127b - Second Term of "Error Correcting Codes"
9 units (3-0-6); third term. Prerequisites: EE/Ma 127a
InstructorRobert J. McEliece
Office: Moore 162 A
Office hours: MWF after class. I will hang around to answer questions,discuss the weather, etc., after each lecture. I will be happy tomeet with students at other times, too. Please schedule these visits withmy secretary Shirley Beatty (162 Moore, shirley@systems, x4715).
Office: Moore 231
Office hours: Friday 4-5 p.m. or e-mail me to arrange an appointment
Xiaoyan (Michelle) Yuan (firstname.lastname@example.org)
Class Meetings: Monday, Wednesday, and Friday from 9:00--9:55 am in Room 080 Moore. I have reserved the room until 10:30, so we should have plenty of time for informal discussions after class.

Grading PolicyThere will be a number of homework assignments, approximately one per week, and one or two software projects. (Details to follow.) On each of these assignments youwill receive a letter grade. Your letter grade in the course will be aweighted average of the grades on these assignments, where each homeworkassignment will have weight one, and each project will have weight five. (I will not count your worst HW.)
Homework Collaboration PolicyI expect you to try to do the problems yourself, since I believe that thismaterial is best learned through problem-solving. If you get stuck, however,I don't object to you asking for help, from another student, from the TA's,or from me, unless the problem is explicitly designated as a "nocollaboration" problem. (In that case, you can only ask the TA's or me, andwe will give only general advice.) Of course, I expect you to write up yourown solutions, and to understand what you hand in.
Late Homework PolicyPlease turn in the homework when it is due! One of the most valuable lessonsyou can learn, at Caltech or elsewhere, is to deliver the goods on time! Anyway, I will normally not grant homework extensions.
