General Description

Reed-Solomon coding is a method of forward error correction in the form of block coding. Block coding consists of

calculating a number of parity symbols over a number of message symbols. The parity symbols are appended to

the end of the message symbols forming a codeword. Reed-Solomon coding is described in the form RS(n,k),

where k is the number of message symbols in each block and n is the total number of symbols in the codeword.

The value t defines the number of symbols that can be corrected by the Reed-Solomon code, where t=(n-k)/2 and

the number of parity symbols is equal to 2t.
