信道相关性对多入多出系统性能的影响

The Impact of Channel Correlation Variation on the Performance of Multiple Input-Multiple Output Systems

通过仿真研究了信道相关性对多入多出系统性能的影响,结果表明,在使用多入多出天线的平坦衰落信道中,影响性能的关键因素是天线位置与本地散射体分布的不同引起的相关性变化.

The performance of multiple inputmultiple output (MIMO) system with channel correlation fluctuation is studied. The simulation results indicate that the performance of MIMO systems in the flat fading environment is primarily relied on correlation variation caused by the different displacements of the antennas and the different distributions of local scattering.
