| 摘 要： | 如何提高无线移动蜂窝网络的覆盖性能一直以来都是个人移动通信技术中的研究热点之一,随着自组网技术的发展,将蜂窝网络与Ad Hoc自组网相结合的多跳通信技术为此问题提供了新的解决方案.本文在选用TD-SCDMA系统移动终端作中继的基础上,主要对系统单蜂窝小区两跳结构的覆盖性能进行了分析和仿真.结果表明,无论采用何种中继节点选择算法,这种由移动终端作为中继者的单蜂窝小区两跳结构的覆盖性能都明显优于无中继单跳小区的覆盖性能,同时,两跳小区的覆盖性能会受到中继节点选择的影响.

| Abstract: | How to improve the coverage of cellular radio networks has now become one of the popular research subjects in the field of wireless communication technology. To deal with this problem, several novel technologies are proposed last decade, among which Multi - Hop technology attracts more and more attentions. In this paper, we investigate the coverage performance of this two - hop relaying by using certain mobile terminals as relay nodes in TD - SCDMA system. Our simulation results show that relaying can improve the performance. Furthermore , this improvement is quite sensitive to the relay node selection scheme. |
