Abstract:
1. An apparatus for correcting and detecting multiple spotty-byte errors within a byte occurred in a limited number of bytes, comprising: an encoding means for generating a transmitted word based on input information data; and a decoding means for inputting said transmitted word where errors occurred in an information transmission channel as a received word and correcting and detecting said errors, wherein said encoding means generates said transmission word by adding check information generated based on a parity check matrix expressing a spotty-byte error control code and said input information data to said input information data, said decoding means comprises a syndrome generating means for generating a syndrome of said received word based on said parity check matrix; and an error correction means for correcting and detecting said errors in said received word based on said syndrome generated by said syndrome generating means, when said input information data is composed of multiple bytes, where b bits (b is an integer that is 2 or more.) is called a byte, errors up to t bits (1≦t≦b) within a byte is called a spotty-byte error, and errors in which a plurality of said spotty-byte errors occurred within a byte is called multiple spotty-byte errors within a byte, said spotty-byte error control code expressed by said parity check matrix corrects μ said value t, said value b, said value p
