Information symbol coding process for use in communication system, involves coding information word of preset length of form belonging to Reed-Solomon code of preset size and length

摘要

The process involves coding an information word of length (k) in a form of word (v) belonging to a Reed-Solomon code of size (k) and length (n). Components of the word (v) situated in preset positions are equal to respective preset constants. The components having fixed value are removed to obtain the word (v) of a length (n) belonging to the code, which constitutes a shortcut code with respect to the code. Independent claims are also included for the following: (a) a coding device having a RAM memory (b) a data processing apparatus comprising a source of information symbols (c) a storage unit having instructions for executing an information symbol coding process.
