1. Channel Capacity

5. Techniques to reduce errors in digital communication systems Automatic repeat request (ARC) Forward error correction (FEC) Channel coding as opposed to source coding ARC is typical of computer systems. FEC is typical of large transmission delay systems. We will concentrate in FEC.

6. Codes

10. http://en.wikipedia.org/wiki/Convolutional_code Rate 1/3 non-recursive, non-systematic convolutional encoder with constraint length 3

11. http://en.wikipedia.org/wiki/Convolutional_code Sixteen-state recursive systematic convolutional (RSC) code.
