多维类正交伪随机矩阵多项式的组合特性研究

研究用于产生多维类正交伪随机矩阵的生成多项式，这既可以由同组的多项式按照顺序的方式组合而成，也可以由不同阶的多项式按照任意的顺序组合而成，同时还可以由多项式的逆组合而成。由不同方法组合而成的生成多项式，经过群变换和数值转换之后得到的多维类正交伪随机矩阵也不同。所以，生成多项式组合方法的多样化，也使其对应产生的多维类正交伪随机矩阵更为丰富，从而得到更多的能应用于码分多址（Code division multiple access，CDMA）等通信系统中的类正交序列。

The Research of Characteristics of Polynomial Combination of the Multi-dimensional Similar-orthogonai Pseudo-random Matrix

In this paper, we research the generator polynomial of Multi-dimensional Similar-orthogonal Pseudo-random Matrix. It can be combined by the same polynomial group in order. It also can be combined by different orders of polynomial in accordance with random order. At the same time, it can be combined by inverse polynomial. The generator polynomial which is combined in different ways can be changed to different Multi-dimensional Similar-orthogonal Pseudo-random Matrix after group transform and numerical transformation. Therefore, the more combinations of polynomial, the more abundant multi-dimensional similar-orthogona pseudo-random matrix which is produced by generator polynomial is. Then we can get more Similar-orthogona Sequences which can be used in CDMA（Code Division Multiple Access） communications systems and so on.
