说明：  The Hamming codes (described in the previous section) are suitable for detecting random bit errors in a sequence of transmitted bits. If the communication medium is prone to burst errors (channel errors affecting contiguous blocks of bits), then the Hamming code may not be suitable. Reed Solomon Codes are linear block codes, a subset of the BCH codes called non-binary BCH. The (n, k) RS code contains k data symbols and n-k parity symbols. RS Codes are also cyclic codes since the cyclic shift of any codeword will result in another valid RS codeword.
