摘要
OTA (over - air)系统是MIMO终端评价方法之一，实现了测量设备周围真实的多径衰落环境，目前正在标准化中。衰落仿真器是MIMO-OTA测量系统之一，通过在终端周围布置一圈的多根天线发射无线电波，在评估区域周围实现理想的传播环境。提出了一种简化的衰落仿真系统结构，并通过计算机仿真和实验对衰落仿真系统的特征值和信道容量进行了性能评价。
Simplified configuration of fading emulator system for MIMO-OTA testing
OTA (Over-The-Air) system, which is one of the MIMO terminal evaluation methods, achieves real multipath fading environment around the measurement device, and it is currently being standardized. Fading emulator, one of MIMO-OTA measurement systems, can achieve the desired propagation environment around assessment area by radio waves radiated from a number of antennas placed on a circle around the terminal. This paper proposes a simplified configuration of fading emulator system, and evaluates the performance in terms of eigenvalues and channel capacity obtained by the computer simulation and experiment.
