基于多入多出(MIMO)散射无线信道模型
提出一种动态MIMO散射无线信道模型
分析散射体及其收发多天线的运动对MIMO无线信道空域相关性及其容量的影响
得出这种影响是由收发天线的初始位置、运动速度及其传播环境决定的.数值模拟验证了这种影响
并指出空域相关性随天线单元间距增大而减小
随散射信号角度扩展增大不是一致减小
存在使相关性达最小的角度扩展值.
A dynamic MIMO scattering wireless channel model is proposed
based on the multiple-input-multiple-output (MIMO) scattering wireless channel model and is used to analyze the effect of mobility of the scatterers and transceiver antennas on the spatial correlation and capacity of the MIMO wireless channels.The conclusion is attained
which states that the effect is determined by original positions of transceiver antennas
the velocity as well as environments.The simulation results validate the effects and show that there exists an optimum angular spread that forces spatial correlation
which decreases with increasing antenna spacing and does not consistently decrease with increasing angular spread
to reach minimum.
