设q为素数幂,q= 12 c2 + 4c + 3,c为整数.本文在Z2 ×(Fq 2,+)中构造了一个含参数(2 q2; q2,q2,q2,q2 − 1; 2 q2 − 2)的差分族.因此,通过应用Wallis-Whiteman阵列,我们获得了上述q的4阶(2 q2 + 1)的Hadamard矩阵。
Let q be a prime power of the form q= 12 c 2+ 4 c+ 3 for c an integer. In this paper we construct a difference family with parameters (2 q 2; q 2, q 2, q 2, q 2− 1; 2 q 2− 2) in Z 2×(F q 2,+). As a consequence, by applying the Wallis–Whiteman array, we obtain Hadamard matrices of order 4 (2 q 2+ 1) for the aforementioned q’s.
