提出了正交码的生成方法，并将其应用于码分多址系统中。这些方法被用来构造所有可能长度达到256的代码。我们还提出了由Kronecker矩阵乘积生成的正交码，称为扩展正交码，用于级联正交序列。该方法允许将单个用户以及用户组(形成微小区、小区扇区或波束)垂直分开。此外，我们还研究了复数、多相和其他正交码设计。
Methods of generating orthogonal codes are presented and applied in CDMA systems. These methods are used in the constructing of codes of all possible lengths up to 256. We also present orthogonal codes generated by Kronecker matrix products, called extended orthogonal codes which are used in concatenating orthogonal sequences. This approach allows individual users as well as groups of users (forming microcells, cell-sectors or beams), to be separated orthogonally. In addition, we examine complex, polyphase and other orthogonal code designs.
