| 摘 要： | 指出现有MIMO理论研究只是在所建立的基带数学模型基础上,依据空分复用(SDM)原理证明了MIMO可增加信道容量.但是它没有给出与该数学模型相适配的、合理的物理模型,导致所依据的SDM无法实现,使MIMO理论在数学层面所导出的信道容量公式在物理上是无法实现的.从天线的物理特性、各种天线阵的波束图、MIMO物理模型的不合...

| Abstract: | It is pointed out that the current MIMO theory bases its study solely on the established mathematical model,and using the space division multiplex(SDM) principle to provet the increase of channel capacity(CC).Unfortunately there is no reasonable physical model matching to that mathematical model,leading to the fact that the SDM cannot be realized in MIMO system.It implies that the CC formula of MIMO system deduced by the mathematical model cannot be realized physically.The infeasibility of MIMO theory is pr... |
