| 摘 要： | 研究了两跳固定中继蜂窝网的频率规划问题.与其他固定中继蜂窝网的研究不同,假设了固定中继节点与其所属基站链路上没有任何性能增强技术,并在此假设条件下,根据复用分割原则,提出了两种新的中继频率规划方案.同时将提出的频率规划方案与基于信道借用的频率规划方案及传统无中继的频率规划方案进行了比较.理论分析和仿真结果表明, 所提出的频率规划方案不但能提高小区边缘用户的服务质量,且与基于信道借用的频率规划方案相比,能够获得更大的系统性能提高.研究结果还表明,为了充分发挥固定中继网络的潜力,有必要在固定中继节点与其所属基站链路上引入性能增强技术.

| Abstract: | The frequency planning for a cellular system enhanced with two-hop fixed relay nodes (FRNs) is investigated. It is assumed that there is no performance-enhancing technique on the base station (BS)-FRN links. Under the assumed condition, two frequency planning schemes are proposed by the principle of reuse partitioning (RP). The frequency planning schemes are compared with the channel-borrowing-based frequency planning scheme and the conventional frequency planning scheme without relaying. Theoretical analysis and simulation results show that the proposed schemes can improve the service quality for mobile terminals close to cell boundaries and provide better performance over the channel-borrowing-based frequency planning. Finally, to fully exploit the potentials of FRN enhanced cellular system, some performance enhancing techniques on BS-FRN links are indispensable. |
