Abstract：With the recent developments of high-mobility wireless communication systems, e.g., high-speed train (HST) and vehicle-to-vehicle (V2V) communication systems, the ability of conventional stationary channel models to mimic the underlying channel characteristics has widely been challenged. Measurements have demonstrated that the current standardized channel models, like IMT-Advanced (IMT-A) and WINNER II multiple-input multiple-output (MIMO) channel models, offer stationary intervals that are noticeably longer than those in measured HST channels. In this talk, we propose a non-stationary IMT-A channel model with time-varying parameters including the number of clusters, powers and delays of clusters, angles of departure (AoDs), and angles of arrival (AoAs). Based on the proposed non-stationary IMT-A channel model, important statistical properties such as the local spatial cross-correlation function (CCF) and local temporal autocorrelation function (ACF) are derived and analyzed. Simulation results demonstrate that the statistical properties vary with time due to the non-stationarity of the proposed channel model. An excellent agreement is achieved between the stationary interval of the developed non-stationary IMT-A channel model and that of relevant HST measurement data, demonstrating the utility of the proposed channel model.
