Judging of the orthogonal system over rings \(\mathbb{Z}_ N\)
The construction and recognition of orthogonal families of functions over the ring \(\mathbb{Z}_N\) are considered. The connection among the orthogonal, independent as well as the partial balance families are established. This yields an algorithm for the construction of orthogonal systems of such functions.
