In wireless communication, MIMO technology can improve performance by offering larger channel capacity without additional bandwidth or transmitting power. This paper presents the measurement of intra-vehicle ultra wideband (UWB) multiple-input multiple-output (MIMO) channels and evaluates channel capacity. The measurement was carried out in time domain for three scenarios: (1) in the car compartment, (2) beneath the chassis, and (3) inside the engine compartment. The results show that MIMO channel capacities increase while using more antennas and the capacity achieved by water filling is larger than that achieved by equal power distribution.
