基于并元加性群的正交码发生器

An orthogonal codes generator based on dyadic additive group

将mn阶并元加性群G={0,1,2,…mn-1}的元依次作为位置的号码(m为素数),给出找出它的mn-1阶子群与陪集位置的简易方法,证明了矩阵的并元加性群扩大法,在此基础上给出正交码发生器的构造图,该编码器结构简单,使用方便,可产生足够多的编码,可用于同步多址CDMA通信中。

To regard elements of mn order dyadic additive group G={0,1,2... mn-1} as position numbers in order( m is prime number), the simple method to search positions of mn-1 order subgroups and its cosets was presented , dyadic additive group expansive method of matrixes was proved, on the basis of this, the structure figure of orthogonal codes generator was drawn. The orthogonal codes generator possess simple structure and it is convenient to use. It may produce enough codes and can be used in spread spectrum synchronous access.
