Abstract
In this paper, the results and analysis of the measured data for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) channels in indoor environment, in presence of pedestrian, are reported. The experiment used 4 sending and 4 receiving antennas and 114 OFDM sub-carriers for each transmission. The mean channel capacity and the dynamic range of the received power increased with the number of pedestrians present within the indoor environment . Each transmitter-to-sender sub-channel had a Signal to Noise Ration (SNR) of 15 db. With three pedestrians, the mean channel capacity rose by up to 2 bps/Hz compared to the vacant room scenario due to the increase in multipath conditions caused by body-shadowing effects. This demonstrates that the use of MIMO in the indoor environment is effective in compensating for the presence of pedestrians.
