Performance Analysis of Two-Hop-Relay WCDMA Cellular Systems

摘要

摘要: 该文首先介绍了一种两跳中继WCDMA蜂窝系统结构，建立了系统的解析模型。然后在这个模型的基础上，分别得到了系统的平均下行传输速率和数据包呼叫请求阻塞概率。最后通过数值计算分析了各种系统参数对两跳中继WCDMA蜂窝系统性能的影响，并和传统非中继WCDMA蜂窝系统以及具有拥塞控制功能的两跳中继WCDMA蜂窝系统进行了比较。

Abstract: This paper firstly introduces a new architecture of two-hop-relay WCDMA cellular system, and builds the analytical model of this system. Then based on this model, the average downlink transmission rate and the call blocking probability of packets of the system are obtained respectively. Finally, through numerical calculation, the impact of the various parameters on the performance of the two-hop-relay WCDMA cellular systems is analyzed, and the systems performance is compared with the traditional WCDMA cellular systems without relaying and the two-hop-relay WCDMA cellular systems with congestion control.
