Special projects: Codes

We've explored several codes already - the Hamming codes, and a fairly broad class of codes called cyclic codes. In this chapter, we will meet some important codes which are in some ways a little more advanced than the ones we've seen already. These new codes will include the alternant codes, lexicodes, extended ternary Golay code, Goppa codes, and low density parity check codes. These sections can be used as a basis for a semester project.
