Title:  New method to design Golay complementary set by paraunitary matrix and its Boolean function.

Abstract: Golay complementary sequences were well studied by Boolean-function generator. Recently, we proposed a new paraunitary-matrix-based construction to generate polyphase Golay complementary sets, in which produces a large number of new Golay complementary set not reported by Boolean-function generator. However, the relationship between the Boolean-function-based construction and paraunitary-matrix-based construction is still unknown. In this talk, I will bridge the sequences constructed by these two methods. Moreover, explicit Boolean representations of Golay complementary sets constructed by Wang and Budisin are derived by the summation of the Boolean functions which is determined by Hadamard matrix involved in the paraunitary-matrix-based construction. It is surprising that the new Boolean function also occur as cosets of the first-order Reed–Muller code. This proposed method can also be used to study complete complementary codes.
