| Abstract(in English) | To achieve high capacity transmission in high frequency usage efficiency, it is valid to use MIMO-OFDM transmission with M-ary modulation. However, to demodulate received signals correctly, we need channel estimation with a high degree of accuracy and high modulation accuracy. In particular, the accuracy of estimation for channel estimation become degraded on high speed and multipath environment and it is also problem to implement channel estimation with the calculated load. For these problems, we have proposed a two-dimensional channel estimation method using parameter table selection. In this paper, we construct the Testbed of MIMO-OFDM transmission systems for high-speed mobile environment with our channel estimation method and evaluate the performance. |
