Abstract：The massive multiple input and multiple output (Massive MIMO) system can provide remarkable space diversity which greatly improves the spectrum and energy-efficiency.A reliable and realistic channel model serves as the enabling foundation for practical design and testing of the communication systems.The properties of Massive MIMO channel based on channel measurement are investigated.The measurement results of channel temporal dispersion characteristics are compared at 1.472 5 GHz and 4.45 GHz in terms of multipath time delay,root mean square (RMS) delay spread and correlation bandwidth.The results reveal that the fading is correlated in some degrees and that the assumptions of unrelated scattering (US) are not hold.
