Abstract :
Current researches on multiple-input multiple-output (MIMO) channel treat it as a kind of Gaussian channel. Without considering the spatial-temporal correlation, considerable deviation exists in output. This paper presents a novel spatial-temporal correlation model (STCM) for MIMO channel modeling. We adopt a correlation matrix to model the spatial correlation at the base and use wave superposition to capture the spatial-temporal correlations at the mobile. Result of simulation shows that the H matrices can construct directly with accurate parameter correlation statistics and spatial-temporal channel correlation may be attained. STCM model minimizes the deviation of conventional model in virtue of the comprehensive consideration of spatial-temporal correlation
