摘要
An isomorphism preserving Hamming distance between two algebraic geometry(AG)codes is presented to obtain the main parameters of Justesen’s algebraic geometry(JAG)codes.To deduce a simple approach to the decoding algorithm,a code word in a“small”JAG codeis used to correspond to error-locator polynomial.By this means,a simple decoding procedureand its ability of error correcting are explored obviously.The lower and upper bounds of thedimension of AG codes are also obtained.
