We compared the average capacities of measured 8×8 MIMO systems with the capacities calculated from a popular stochastic MIMO model. This model separates the influence of fading from the correlation at transmit (TX) and receive (RX) arrays. By using directional RX antennas and a virtual 20×10 TX array with omni antennas we measured the MIMO channel at different RX positions in an indoor office scenario at 5.2GHz. For low correlation at the receiver and transmitter the model fits very well. But
