A Study on the Construction Method for Orthogonal Complementary Set Group Based on Complementary Sets

A study on the construction method of the orthogonal complementary sets group used for CDMA coding in the sequence analysis, meanwhile, we make the analysis of the relation between complementary Set and the orthogonal complementary Sets group. Furthermore, we design the method which can be used to constitute the orthogonal complementary sets group by the known complementary set, put forward the necessary and sufficient condition for two orthogonal complementary sets, thus, we get the uniqueness of the orthogonal complementary sets group and the largest value of the number of complementary set. This construction method has a strong theoretical and practical significance, meanwhile, which have laid a solid foundation for the further study on related theories.
