This paper presents detailed results of 11 GHz band outdoor transmission experiments employing 8 × 16 MIMO-OFDM for 10 Gbps super high bit rate mobile communications. Super high bit rate mobile communications have been studied for future mobile communications, and to verify the feasibility, outdoor transmission experiments were performed. A mobile station (MS) with 8 transmitter antennas traveled along a measurement course while a base station (BS) with 16 receiver antennas stored the received signals, and then the throughput performance levels were evaluated by demodulating them in an off-line mode. This paper introduces specifications and a hardware configuration for the 11 GHz band 8×16 MIMO-OFDM experimental system with a signal bandwidth of 400 MHz. In addition, it presents the SNR distribution and delay spread that are calculated from the received signals in the measurement course used in the outdoor experiments. The experimental results show that for 11.8 Gbps transmission with 8 streams, 64QAM, and the coding rate of 3/4, throughput of greater than 10 Gbps is achieved in an 11 GHz band outdoor mobile environment.
