Gaussian Angular Distributed MIMO Channel Model

This paper presents an AR(3) based state space MIMO channel model, in which the joint angular power PDF of AOA and AOD is assumed to be Gaussian. The channel´s spatio-temporal correlation is approximated as the product of an AR(3) process and the corresponding spatial antenna correlation. A state-space representation is employed to model the temporal dynamics of the MIMO channels. To obtain the appropriate spatio-temporal channel correlation in the simulated channels, a correlated innovation process is used.
