WebI am trying to construct a binary cyclic code of length 257 with rate strictly greater than 1 2 and distance 18 or more. I read about general BCH codes and implemented it. The multiplicative order of 2 modulo 257 is 16. So, I realize GF ( 2 16) as GF ( 2) [ t] / ( t 16 + t 5 + t 3 + t 2 + 1). I choose a 257 -primitive root of unity in GF ( 2 16).
