纠错码与B_h序列

Error correcting codes and B_h-sequences

Harm Derksen

摘要:

利用加性数论中Bose和Chowla的一种构造方法构造了非线性二进制纠错码。我们的方法扩展了Graham和Sloane等重码的构造。新的码改进了7168个最好的h-纠错码中的1028个,其字长最多为512,h最多为14。我们给渐近比较缩短BCH码。表的新的下界为“A(n,d)”。

英文摘要:

We construct error correcting nonlinear binary codes using a construction of Bose and Chowla in additive number theory. Our method extends a construction of Graham and Sloane for constant weight codes. The new codes improve 1028 of the 7168 best known h-error correcting codes of wordlength at most 512 and h at most 14. We give assymptotical comparisons to shortened BCH codes. Tables of new lower bounds for "A(n,d)" are included.
