ovsf
- orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutuall

CDMAPVPONPIMSI_auth
- 本文着重描述了基于CDMA 1 X VPDN网络具体连接建立的步骤和实际应用。提出具体的解决IMSI认证和地址绑定的实现方案，提供了 实验环境拓扑。并给出在试验环境下路由器的基本配置并对主要的配置加以说明。其中lMSI认证实现的关键是利用RAD I US服务器。试验环境使用的软件是FreeRadius免费软件，正式组网时可利用企业现有的RAD I US服务器或安装免费的RAD I US软件，从而低成本解决了该问题。上述解决方案经过实验网测试。系统运行稳定。证明有效可行。-This artic
