In this paper, we propose two new construction methods for quaternary Hadamard matrices. By the first method, which is applicable for any positive integer n, we are able to construct a quaternary Hadamard matrix of order 2n from a binary sequence with ideal autocorrelation. The second method also gives us a quaternary Hadamard matrix of order 2n from a binary extended sequence of period 2n – 1, where n is a composite number.
