固定协作中继蜂窝小区资源分配研究
首发时间:2009-07-08
摘要:通过在蜂窝系统中部署中继站,能够利用中继传输有效地提高系统性能。本文提出了一种固定协作中继的OFDMA蜂窝小区模型。相比较传统的单中继的小区结构,协作中继结构能够利用中继之间的协同传输提高系统性能。针对这种系统模型,提出了一种新的,适用于该模型的信道复用和信道分配策略,并且分析了在该策略下的系统干扰和信道容量。数学分析表明,在该模型下,采用本文提出来的策略,系统性能较传统两跳OFDMA中继系统性能有较大的提高。

Frequency Allocation Scheme for Cooperation-Relay
Abstract:The integration of multi-hop capabilities in OFDMA cellular systems through the deployment of relay stations could improve the performance of system. In this paper, a novel cooperation-relay station model in the cellular mobile communication system is addressed. Compared with the traditional signal fixed relay model, the proposed model could use the cooperation in relay-cluster to improve the performance of system. In view of this model, a resource allocation scheme is addressed. The co-channel interference and system capacity is mathematically analyzed. Mathematical analyze result show that, the new scheme in cooperation-relay cellular system outperforms traditional fixed-relay system.
Keywords: cooperation-relay frequency allocation co-channel interference channel capacity
