摘　　要：在散射体丰富的环境中,信道容量受终端移动的影响很大,为此提出一种基于动态的多人多出(MIMO)散射无线信道模型,分析了移动终端对该无线信道容量的影响,并讨论了在移动过程中进行天线选择为系统性能带来的提升.仿真结果表明,信道容量随着天线单元间距的增大而增大,随散射信号扩展角度的变大而增加,移动环境下的信道容量要小于准静态环境下的信道容量,且动态天线选择能够有效提升系统容量.The channel capacity will be greatly influenced in the environment where was surrounded by large amount of scatters,so a new channel model was proposed which based on dynamic MIMO scattering wireless channel.The influence on wireless channel capacity was analyzed which was brought by mobile terminal,and the promotion brought by the antenna selection during moving was discussed.The simulation results show that the channel capacity will become larger with the antenna spacing and expansion angle increase.The channel capacity is lower in mobile environment than that in semi-static environment,and the antenna selection can improve the system capacity effectively.
