Right - it started life as a graffito, but now has content. Keep.

In the article at present it is stated that a block code is characterised by encoding the information symbols consecutively. I have doubts if that is correct. In my opinion, the main characterisation of a block code is that it is a fixed length channel code (unlike source coding schemes such as Huffman coding, and unlike channel coding methods like convolutional encoding).

In my opinion it is however possible that a block code takes a k-digit information word, and transforms this into an n-digit codeword, without there being the possibility to a symbol by symbol encoding of the information digits. Bob.v.R 11:26, 17 September 2005 (UTC)

No answer sofar. I will now in the article make the distinction more clearly between the practical and the theoretical definition. Bob.v.R 17:42, 23 September 2005 (UTC)

## Cleanup Template

This article lacks important information, and some of that it provides is incorrect. Nageh (talk) 17:33, 9 October 2009 (UTC) Particularly it needs to cover block codes in more detail, introduce linear and non-linear codes, and important theoretical bounds to block codes such as the Hammington and Singleton bounds.

## Distance d of two Blockcodes

How is the Distance of two Blockcodes defined? What is the Distance of (2,0) and (0,0)? —Preceding unsigned comment added by 84.140.251.84 (talk) 20:34, 3 February 2010 (UTC)
