Channel models of massive MIMO.

Modeling method	Category	Property
CBSM	i.i.d. Rayleigh channel model	Elements of fast fading are i.i.d. complex Gaussian variables
	Correlation channel model	Contain correlation between transmit antennas or/and receive antennas
	Mutual coupling channel model	Consider antenna impedance, load impedance, and mutual impedance
GBSM	2D channel model	Propagate beam on 2D plane, such as linear array
	3D channel model	Propagate beam on 3D plane, such as spherical, rectangular, and cylindrical array
