This paper deals with MIMO channel modeling in underground transport environments like tunnels for various antenna array configurations at both the transmitting and receiving sides. MIMO channel matrices have been computed with a full 3D ray-tracing and modeled using correlation based analytical models, like the Kronecker and the Weichselberger models. First, two different modeling strategies are investigated. The first one is computed over all the tunnel length. The second one takes into account the transmitter-receiver distance. In the latter solution, it is possible to isolate specific areas in the tunnel with different correlation properties and take them into account in a system simulation. Then, these two modeling are compared in terms of mean channel capacity results.
