In this contribution the radio channel model proposedin [1] is extended to include multiple transmitters and receivers.The propagation environment is modelled using randomgraphs where vertices of a graph represent scatterers and edgesmodel the wave propagation between scatterers. Furthermore,we develop a closed form analytical expression for the transfermatrix of the propagation graph. It is shown by simulation thatimpulse response and the delay-power spectrum of the graphexhibit exponentially decaying power as a result of the recursivescattering structure of the graph. The impulse response exhibitsa transition from specular to diffuse signal contributions asobserved in measurements.
