Abstract: A kind of multiplication of orthogonal arrays is presented by exploring orthogonal decomposition of projection matrices. Using this multiplication, one can construct some new larger orthogonal arrays from smaller ones.

Key words: Mixed-level orthogonal array, Projection matrix, Permutation matrix, Kronecker sum
