若干达到界的正交阵列

Several Orthogonal Arrays Achieving Bounds

构造了三类新的正交阵列,它们分别达到Rao-界和文献[9]中提到的两个界.另外,利用这些正交阵列可以构造一些相应的线性码,这些线性码还能够达到编码理论中的Griesmer界.

Three new classes of orthogonal arrays that meet the equality of Rao-bound and other two bounds proposed in [9] were constructed, and these resulting orthogonal arrays can construct linear codes that reach the equality of Griesmer bound in Error-Correct Code Theory.
