Abstract :
In this paper, to evaluate the basic performance of MIMO cooperative transmission systems, a simple prediction method which calculation complexity is decreased for evaluating indoor MIMO cooperative transmission is proposed. 5.2 GHz indoor MIMO propagation measurements are carried out in line of sight condition. And the frequency utilization efficiency and eigenvalues are evaluated by measurement data. Simple prediction method of MIMO channel matrix, which takes into account the phase difference of direct waves based on the antenna position, is used to simulate the MIMO channel. The simulation results are then compared to the measurement results. Based on this comparison the proposed prediction method can accurately estimate the characteristics of indoor MIMO cooperative transmission systems.
