【Abstract】 In this paper, a MIMO channel model in the presence of polarization diversity is presented, the spatial correlation between signals and the channel capacity is analyzed, and the effect of polarization angle between receiving antennas on the spatial correlation and the channel capacity is investigated. Simulation results show that MIMO wireless system using polarization diversity is of excellent fading characteristic,and channel capacity is increased effectively.更多还原
