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. |
