Abstract :
Effects of pedestrian movement on multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) channel capacity have been investigated using experiment and simulation. The experiment was conducted at 5.2 GHz by a MIMO-OFDM packet transmission demonstrator using four transmitters and four receivers built in-house. Geometric optics-based ray-tracing technique was used to simulate the experimental scenarios. Changes in the channel capacity dynamic range have been analyzed for different numbers of pedestrian (03) and antennas (24). Measurement and simulation results show that the dynamic range increases with the number of pedestrians and the number of antennas on the transmitter and receiver array.
