Abstract :
A theoretical model is proposed for multi-input-multi-output (MIMO) mobile-to-mobile (M-to-M) Rayleigh fading channels, such that the complex faded envelope does not depend on the distance between scatterers and antenna elements. From this model, a closed-form joint space-time correlation function is derived for 2-D non-isotropic scattering environment. Also, a space-frequency power density spectrum of the complex faded envelope is derived, assuming 2-D isotropic scattering environment. Finally, a statistical simulation model for MIMO M-to-M Rayleigh fading channels is proposed. The space-time correlation function of the simulation model is derived and verified by simulation, and an adaptive method for choosing the number of scatterers in simulations is proposed. The results show that the statistical simulation model is a good approximation of the theoretical model
