Comma code

A comma code is a type of prefix-free code in which a comma, a particular symbol or sequence of symbols, occurs at the end of a code word and never occurs otherwise.^[1]

For example, Fibonacci coding is a comma code in which the comma is 11. 11 and 1011 are valid Fibonacci code words, but 101, 0111, and 11011 are not.

Examples

• Unary coding, in which the comma is 0.
• Fibonacci coding, in which the comma is 11.

• Self-synchronizing code
