WebA formula for the order of the automorphism group of a binary linear constant weight code in terms of its parameters is presented, which is a key step to determine more algebraic structures on constant weight codes with given parameters. We give a characterization for the binary linear constant weight codes by using the symmetric difference of the … Web2 binary linear code, where D0 D. Writing n= NlogNand considering the case where K= N D+1, we observe that the transformation of a Reed-Solomon code to a binary code results in a [n;n (D 1)logN; D] 2 code. The resulting binary code has a decent rate, but it is not optimal: BCH codes are even better, as they are [n;nd D 1 2 elog(n+ 1); D] 2 ... granby college of science and technology
