Accurate characterization of multiple-input multiple-output (MIMO) fading channels is an important prerequisite for the design of multiantenna wireless-communication systems. In this paper, a single-bounce two-ring statistical model for the time-varying MIMO flat fading channels is proposed. In the model, both the base and mobile stations are surrounded by their own ring of scatterers. For the proposed...
In this paper, some important second-order statistics such as the correlation coefficient, level crossing rate, and average fade duration of eigen-channels, are studied, in time-varying Rayleigh multiple-input multiple-output (MIMO) channels, assuming a general non-isotropic scattering environment. Exact closed-form expressions are derived and Monte Carlo simulations are provided to verify the accuracy...
In this paper, the second-order statistics such as the autocorrelation function and correlation coefficient of the instantaneous mutual information (IMI) are studied, in 2times2 multiple-input multiple-output (MIMO) time-varying Rayleigh flat fading channels, assuming general non-isotropic scattering environments. Exact closed-form expressions are derived, as well as asymptotic approximations in low-...
