In this paper we address the problem of channel parameter estimation and tracking for multiple-input-multiple-output (MIMO) OFDM systems where the channels are spatially correlated. Starting from the OFDM transmission model with independent MIMO channels, we derive a state-space model that accounts for a spatial correlation structure. An advanced spatial MIMO correlation model validated by measurements is used. The parameters describing the dynamics of the state (i.e. the state transition… CONTINUE READING
