Template:Other uses Template:No footnotes In communication, a code word is an element of a standardized code or protocol. Each code word is assembled in accordance with the specific rules of the code and assigned a unique meaning. Code words are typically used for reasons of reliability, clarity, brevity, or secrecy.

Background Edit

Coding Theory is the branch of mathematics that covers source codes and channel codes.

A channel code contains redundancy to allow more reliable communication in the presence of noise. This redundancy means that only a limited set of signals is allowed: this set is the code.

A source code is used to compress words (or phrases or data) by mapping common words into shorter words.

Procedure words are used for voice communication on noisy channels.
