A Note on Error Control for Image Recording Systems

We propose an error control method to implement encoders and decoders inserting one byte parity between information symbols inside each C1 codeword. One byte parity is designed by RS code over GF(28) with minimum distance 2. The parity prevents C1 codeword from miscorrecting for C1 decode. Hardware to implement the parity encoder is devised to make C1 check words by encoding information words which include parity words. Numerical results show that the probability of miscorrection is restrained enough under the detectable level, and good coincidence with simulation results.
