摘要

研究了二元等距码、等重等距码及其距离分布的Q-变换。通过使用Q-变换分布的性质

研究了二元等距码和等重等距码的最大码字数并得到2个新的上界

这些上界在某些情况下优于已知的结果。

Abstract

Q-transform of distance distribution of binary equidistant codes and equidistant constant weight codes were studied. By employing the properties of Q-transform

the maximum number of codewords of binary equidistant codes and equidistant constant weight codes were studied and two upper bounds were then obtained. These two bounds are better than previous known results in certain cases.
