Abstract :
The MIMO OTA (over the air) measurement systems, emulate the propagation environment in premises, are actively discussed. The propagation environment emulated by the MIMO OTA system is usually easy to re-produce and can precisely compare the performance of different antenna configurations or terminals under exactly the same propagation environment. This paper investigated the effect of vertical angle spread of multi-cluster on MIMO-OTA ( multi-input multi-output-over the air ) spatial channel emulation. Two models which have two clusters are compared with the single cluster model, in terms of correlation coefficients as well as average channel capacity.
