| Abstract(in English) | This paper presents laboratory and field experimental results on high-speed packet transmissions of greater than 2.5Gbps in a 100MHz channel bandwidth, i.e., the frequency efficiency of 25 bit/second/Hz, for the downlink OFDM radio access. We apply 6-by-6 MIMO multiplexing using Maximum Likelihood Detection employing QR decomposition and the M-algorithm (QRM-MLD) with adaptive selection of the surviving symbol replica candidates (ASESS), 64QAM modulation, and Turbo coding with the coding rate of R=8/9 to achieve an extremely high frequency efficiency level. In the field experiments conducted in the Yokosuka Research Park (YRP) district of Yokosuka city, we show that the measured throughput of greater than 2.5Gbps is achieved at the probability of approximately 85% over the measurement course where the maximum distance from the cell site is approximately 200m at the speed of 5km/h with the total transmission power of 19W. |
