Talk:Coding theory

From Wikipedia, the free encyclopedia

Coding Theory generally refers to the two subjects Claude Shannon treated, Source (Compression) and Channel (error correcton). Cryptography is a different subject all together.

[edit] .

I'm a bit of a neophyte here, but would it be proper to mention the sub-categories of coding theory as:

1) Compression coding 2) Coding for secrecy (cryptography) 3) error correction/detection 4) any others?

It sorta does, but its not explicit

Are compression and crypto part of coding theory? Maybe they are, but I think of coding theory as dealing with communications channels. Compression and crypto are independent of communications. Mirror Vax 08:27, 7 May 2005 (UTC)

[edit] Merge with "code" ?

Suggest this article should be merged with code. Both cover much the same territory, and both could use some beefing up.

This article goes into rather more detail, but that may be better devolved down to data compression and error correction.

On second thoughts, maybe not. But then there needs to be some refactoring and clearer definition between the two. Jheald 22:39, 6 March 2007 (UTC)

[edit] Expand section tag

I have tagged the "source coding" section as could do with some expansion.

Source coding now redirects to data compression. Which I think is probably correct for the term overall; but requires that we need to make sure that material about the code-level aspects of source coding is still highlighted; and that this article takes up some of the slack too.

Relevant material that should be pointed to might include variable length codes, prefix codes, Kraft inequality, Shannon's source coding theorem, ... more? -- Jheald 22:39, 6 March 2007 (UTC)
