| 摘 要： | 提出了一种分布式MIMO信道模型,其中包含了路径损耗、相关阴影衰落与相关小尺度衰落,并通过Monte Carlo仿真,比较分析了相关小尺度衰落和相关阴影衰落对分布式MIMO信道容量的影响,并研究了空间阴影衰落相关条件下分布式MIMO信道容量空间分布的特点.仿真实验结果表明,提出的分布式MIMO信道模型能够有效降低小尺度衰落相关性和阴影衰落相关性的影响.图7,参11.

| Abstract: | In this paper,a distributed Multiple Input Multiple Output(MIMO) channel model which comprises path loss,correlated shadow fading and correlated small scale fading was proposed.The impact of fading correlation on the capacity of distributed MIMO channels was investigated and compared carefully by Monte Carlo simulations,and the characteristics of capacity space distribution of distributed MIMO channels with spatial shadowing correlation were obtained.The simulation result indicate that the proposed distributed MIMO channel model effectually reduce the impact of low fading correlation on the channel capacity.7figs.,11refs. |
