| 摘 要： | 随着移动通讯技术发展,传输业务已由单一速率的话音拓广为不同速率的话音、数据与图像的多媒体业务。为了区分不同类型速率业务,每种业务要有不同的地址码,而且为了防止不同类型速率业务之间的干扰,其地址码的互相性须为零,即满足彼此正交。移动信道的传输带宽是固定的,为满足信道传播,不同业务、不同信息速率要采用不同长度的正交码。沃尔什(Walsh)正交码是一种理想选择。

| Abstract: | With the development of mobile communication, transimission businesses have been expanded into multimedia business. In order to differ different businesses every business has different access code whose multucality is zero , which is orthogonal each other. Walsh's orthogonality code is the ideal choice. |
