| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In order to realize 10 Gbps super high bit-rate mobile communications, this report introduces detail of indoor 8x16 MIMO-OFDM transmission experiment. More than 10 Gbps super high bit-rate mobile communications have been studied to achieve higher bit-rate in mobile communications. In order to verify its feasibility by experiment, 11 GHz band 8x8 MIMO-OFDM experimental system with 400 MHz bandwidth has been developed, and 10 Gbps transmission has been achieved in laboratory experiments by the RF cable connection. 8x16 MIMO-OFDM experimental system has been developed by enhancing the conventional 8x8 MIMO-OFDM experimental system, and this report presents both configuration and performances of the experimental system. Since changing the clock signal which is input to the 800 MHz-sampling ADC in receive baseband (BB) circuits causes the sampling timing offset, the experimental system compensates for it by using the pilot signals. It is also shown that the experimental system can attain error vector magnitude of 2.57 \% by employing calibration for the BB circuits and radio frequency (RF) circuits. Moreover, by using the developed experimental system, 10 Gbps indoor transmission experiment was conducted in line of sight (LOS) propagation environment. The experimental results demonstrate that the experimental system using both 64QAM and the turbo code with coding rate of 3/4 can realize more than 10 Gbps throughput by employing turbo detection when SNR is equal to or higher than 18 dB. In addition, this report shows throughput performances when the number of receive antennas is reduced and both vertical and horizontal polarization is used, and clarifies experimental condition under which 10 Gbps throughput can be achieved in the indoor LOS propagation environment. | |
