A VECTOR CHANNEL MODEL WITH STOCHASTIC FADING SIMULATION

The simulation of wireless communication systems with multiple antennas requires a spatial channel model which reasonably characterizes the space and time variant effects of the mobile radio channel. This paper describes a vector channel model with stochastic fading simulation, which combines several advantages from purely stochastic and geometrical channel models. The resulting model is consistent with real world wireless channel characteristics and enables numerically efficient bit-level simulations. The channel model enables the investigation of several aspects of space-time-processing techniques. This includes the performance evaluation of space-time algorithms in dependence on time varying spatial channel characteristics and fading correlation effects between the antennas as well as the user tracking and separation abilities of those algorithms.
