摘要

当前这一代无线网络都是以话音为主要业务来设计的。它们不适合支持高数据流量。第三代标准的提出是为了满足移动电话日益增长的数据流量需求。宽带码分多址(WCDMA)是未来蜂窝网络和个人通信系统中很有前途的无线接入技术。本文研究了宽带CDMA网络前向链路的资源分配问题。假设数据速率分别为9.6 kbit/s、144kbit /s和384kbit /s的三类用户。在基站总发射功率受限的约束下,提出了一种动态与静态混合算法。比较了不同流量类别的性能。对语音和数据流量进行了比较研究。

Strategies for resource allocation in wideband CDMA networks for high data rate applications
Present generation wireless networks are being designed considering voice as the primary traffic. They are not suitable to support high data traffic rate. Third-generation standards are proposed to meet the increasing data traffic demand over mobile telephones. Wideband code division multiple access (WCDMA) is a promising technique for radio access in future cellular networks and personal communication systems. This paper deals with the problem of resource allocation in the forward link for wideband CDMA networks. Three types of user classes are assumed with data rate of 9.6 kbit/s, 144 kbit/s and 384 kbit/s respectively. A mixed dynamic and static algorithm is proposed, under the constraint that the base station is total transmitted power-limited. The performance of different classes of traffic is compared. A comparative study for voice and data traffic has been carried out.
