18.413 Announcements

• (4/16/04): Here is a data point for small project 3: At 3 dB, the ber should be around 0.005.

• (4/6/04) I slightly revised the end of the notes for lecture 14.

• (3/18/04) I added a link to some course materials at the top of this page.

• (3/16/04) I put a reference on LDPC codes on the Stellar course web page: http://stellar.mit.edu/S/course/18/sp04/18.413/materials.html.
  Note: I do not suggest making the graph the way that is suggested in this paper.

• (3/16/04) If you email me your graph in a reasonable format before Thursday's class, I will check it for you.

• (3/16/04) In answer to suggestions/questions from last week:
  • Yes, I will raise your grade if you turn in a revised Small Project 2.
  • If you get lost in class, I suggest asking a question. Even a question that you already know the answer to may slow me down enough for you to figure out what is going on.

• (3/16/04) I've set up a bulletin board that can be used for discussion of material. This might be a good way for those of you who miss class to find others with notes! It looks like part of a larger web page, but this is the only part of it that I indend to set up. You all should be able to access it.

• (3/16/04) You should now all be able to use longjobs on athena. Here are official instructions on using longjobs. Please check soon to see if you are really signed up to use them, because it can take a (working) day to adjust the list. You can check the status of your account by typing
