A geometry-based reference model for Second Order Scattering Fading (SOSF) distributed multiple-input-multipleoutput (MIMO) channels is proposed for mobile-to-mobile scenarios. From this model, a spatial correlation function is derived. The time-variant nature of channel statistics is modeled by using a Hidden Markov Model (HMM) based approach. The proposed method enables to implement a generator of channel realizations for a wide range of indoor MIMO channels, including Fixedto- Mobile and Mobile-to-Mobile transmission; Rician, Rayleigh, Double Rayleigh, Second Order Scattering fading, etc.
