| Abstract(in English) | Recently, MIMO cooperative transmission system for achieving high speed data transmission is studying. Up to now, frequency utilization efficiency of MIMO cooperative transmission system have been studied by measurement or simulation side. However, there are few simultaneous studies of both measurement and simulation. In this paper, Indoor MIMO propagation measurement campaign is carried out and frequency utilization efficiency and eigenvalue is evaluated by measurement data. Then, MIMO channel is simulated by nakagami-rice fading model which take account of phase difference of direct wave by antenna position and simulation results are compared with measurement result. As a result, this nakagami-rice fading model can estimate accurate MIMO cooperative transmission channel matrix. |
