在本文中，一个码分多址（CDMA）蜂窝系统与各种业务类型的性能进行了研究。流量整合和资源管理是下一代综合业务无线网络设计中的两个主要问题。为了提供交通整合的设计准则，线速率（在无线电信道中的实际传输比特率）的选择对系统容量的影响进行检查。由于在CDMA系统中，来自一个特定用户的信号在整个可用带宽上扩展，因此用户占用的实际带宽资源取决于用户的发射功率量。在本文中，我们还讨论了如何分配合适的功率电平不同的流量类型。提出了一种针对多种业务类型的功率分配优化方法。
In this paper, the performance of a code-division multiple-access (CDMA) cellular system with various traffic types is examined. Traffic integration and resource management are two major issues in the design of the next generation of wireless networks with integrated services. To provide design guidelines for traffic integration, the impact of the line rate (actual transmission bit rate in the radio channel) selection on the system capacity is examined. Since in a CDMA system the signal from one specific user is spread over the entire available bandwidth, the actual bandwidth resource occupied by a user depends on the amount of the transmission power of the user. In this paper, we also address how to assign suitable power levels to the different traffic types. A method for optimizing the power assignment for multiple traffic types is developed.
