| 摘 要： | 通过理论推导和仿真对一个存在同频干扰的上行蜂窝网中的合作多输入多输出(MIMO)系统的信道容量进行了研究,仿真结果表明由于严重的同频道干扰,整个上行蜂窝系统无法实现全频率复用.提出了一种基于分数频率复用(FFR)与合作MIMO相组合的网络结构以及两种系统时频资源分配方案.信道容量计算结果显示:考虑同频道干扰时,对于信道...

| Abstract: | The capacity of a cooperative multiple-input and multiple-output(MIMO) system with cochannel interference in uplink cellular networks is studied through theoretic derivation and simulation.Simulation results show that the universal frequency reuse cannot be realized because of severe cochannel interference.This paper describes a combined system based on fractional frequency reuse(FFR) and cooperative MIMO with two kinds of time and frequency resource allocation schemes.Simulation results show that with the ... |
