| Abstract(in English) | We can realize high-speed communications with MIMO systems that have multiple antennas at both transmitter and receiver. For a downlink channel in a MIMO system, we apply E-SDM using adaptive modulation in which communication speed is changed according to the channel condition. In this case, assuming packet transmission, we apply a maximum throughput criterion for the adaptive modulation. In this paper, we evaluate the throughput performance of E-SDM transmission with adaptive modulation by using an indoor testbed. Because computation load with conventional adaptive modulation is heavy, it is reduced by simplification. Additionally, we show that linear extrapolation that compensates errors caused by channel fluctuation works in dynamic fading environments. |
