Research on Spatial Correlation of MIMO Channel Model in Coal Mine

This paper establishes MIMO channel model of coal mine,and deduces the spatial correlation function of the channel model.The impact of the antenna distance between transmission antennas and receiver antennas on spatial correlation is also analyzed.On the basis of MIMO channel model,the impact of the space-time correlation of mine MIMO channel on the system BER is discussed.The simulation results show that the higher space-time correlation of MIMO channel in coal mine is,the bigger the system BER is.
