摘要

针对中继网络的两跳特性

提出一种多小区中继网络两跳速率匹配资源分配算法。首先

在第一个子时隙内各小区独立地为小区中所有用户分配子载波

并根据子载波分配结果

建立基于非合作博弈的功率分配模型;然后

由第一跳资源分配结果对第二跳速率匹配

自适应地为中继分配资源以满足边缘用户的速率需求。仿真结果表明

该算法在满足边缘用户速率需求的前提下

进一步提高了中心用户的吞吐量

同时降低了系统的发射功率

从而提升了系统性能。

Abstract

In the light of the two-hop characteristics of relay networks

this paper proposes a resource allocation algorithm based on two-hop rate matching for multi-cell relay networks.It first independently allots subcarriers to all the users in every cell within the first sub-slot and builds a non-cooperative game-based power allocation model on the basis of the above allocation results.Then

it matches the second hop rate with the first hop resource allocation result

adaptively allotting resource to relay so as to meet the rate demand of the edge users.Simulation results demonstrate that while meeting the demand of the edge users for rate

the proposed algorithm further improves the throughput of the center users and reduces the system transmitting power

thus improving the system performances.
