摘要
为固定中继蜂窝网络提供了一种新的性能分析方案,该方案以引入未来将广泛使用的MIMO天线系统为出发点,通过分析在不存在固定中继和存在固定中继两种情况下系统信道容量的变化,考察固定中继蜂窝网络架构的优越性。通过SIMO MISO和MIMO各种情况下的信道容量计算,运用蒙特卡罗方法,得出最后的数值结果。
This paper proposes an analysis scheme for the fixed relaying cellular radio system （purposely on the Carleton University＇s Model）. This scheme is based on the apphcation of MIMO smart antenna system, which is very potential and widely used in future wireless communication. The superiority of fixed relaying cellular network structure is investigated by analysing the changes of channel capacities of systems with FRN and without FRN. Theoretical calculations of channel capacity in SIMO, MISO and MIMO are provided, and the final numerical results are produced by Monte Carlo method.
