Returns a byte string with the k message bytes and n-k parity bytes at the end. If a message is < k bytes long, it is assumed to be padded at the front with null bytes (ie, a shortened Reed-Solomon code). The sequence returned is always n bytes long.

WebJun 5, 2012 · Introduction. Reed–Solomon codes are error-correcting codes defined over large alphabets. They were among the early constructions of good codes (1959), and are now one of the most important classes of error-correcting codes for many applications.

WebSolomon codes are modelled by adding Reed Solomon encode blocks at the beginning of the transmission and the Reed Solomon block decodes at the end of the transmission. In the encoding block, the transmitted messages divided into separate data blocks. The encode block is a systematic code which means that the encoding process does not
