More on the distance distribution of BCH codes
Osnat Keren, Simon N. Litsyn · IEEE Transactions on Information Theory · 1999
We derive a new estimate for the error term in the binomial approximation to the distance distribution of BCH codes. This is an improvement on the earlier bounds by Kasami-Fujiwara-Lin (1985), Vladuts-Skorobogatov (1991), and Krasikov-Litsyn (1995).
