  • Abstract
    Recently Kasami {em et al.} presented a linear programming approach to the weight distribution of binary linear codes [2]. Their approach to compute upper and lower bounds on the weight distribution of binary primitive BCH codes of length 2^{m} - 1 with m \\geq 8 and designed distance 2t + 1 with 4 \\leq t \\leq 5 is improved. From these results, the relative deviation of the number of codewords of weight j\\leq 2^{m-1} from the binomial distribution 2^{-mt} \\left( stackrel{2^{m}-1}{j} \\right) is shown to be less than 1 percent for the following cases: (1) t = 4, j \\geq 2t + 1 and m \\geq 16 ; (2) t = 4, j \\geq 2t + 3 and 10 \\leq m \\leq 15 ; (3) t=4, j \\geq 2t+5 and 8 \\leq m \\leq 9 ; (4) t=5,j \\geq 2t+ 1 and m \\geq 20 ; (5) t=5, j \\geq 2t+ 3 and 12 \\leq m \\leq 19 ; (6) t=5, j \\geq 2t+ 5 and 10 \\leq m \\leq 11 ; (7) t=5, j \\geq 2t + 7 and m=9 ; (8) t= 5, j \\geq 2t+ 9 and m = 8 .
