摘要
利用群环、特征和等代数方法,证明了对于任意的n及奇素数p≠1(mod 8),不存在任何类型的体积为2×2×pn的广义最佳二进阵列,并给出了体积为2×2×2n的广义最佳二进阵列存在的充要条件.所用方法适用于一般最佳信号的存在性研究.
By the tools of group rings and character sums, it was shown that there didn't exist any type of Generalized perfect binary arrays of order 2×2×p^n for any n and any odd prime p≠1 (mod 8). Meanwhile, the existence problem of Generalized perfect binary arrays of order 2×2×2^n was solved. The methods could also be used to study other perfect signals.
