TD-SCDMA系统的反向链路小区覆盖范围的分析

Analysis of Cell Coverage for TD-SCDMA Uplink Channel

基于持续服务中断原则对TD-SCDMA系统的反向链路小区覆盖范围进行了理论分析,并给出了数值结果。数值结果表明,由于使用多用户联合检测技术抑制多址干扰,随着激活用户数的增加,小区的有效覆盖范围几乎保持不变;扩频因子越小的业务所对应的小区覆盖范围越小。

It presents a useful methodology of cell coverage estimation for TD-SCDMA cellular network based on a duration outage criterion, and gives quantitative results. Results show that cell coverage almost remains constant as the number of active users in the cell increases due to the usage of joint detection technology to suppress multiple access interference. Results also show that the cell coverage for small spreading factor services is necessarily smaller than cell coverage for large spreading factor services.
