On the distance distribution of BCH codes
Osnat Keren, Simon N. Litsyn · 2002
A new estimate for the error term in the binomial approximation to the distance distribution of BCH codes is presented. This is an improvement on the earlier bounds by Kasami-Fujiwara-Lin (1985), Vladuts-Skorobogatov (1998) and Krasikov-Litsyn (1995).
