For the analysis and design of Multiple-Input Multiple-Output (MIMO) wireless communication systems with frequency diversity features, e.g., MIMO-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems, it is often desirable to develop a channel model that can characterise the three- dimensional (3-D) space-time-frequency (STF) correlation properties over the links of the underlying MIMO channels. In this paper, we propose a generic 3-D STF correlation model, which includes many well-known existing models as special cases, with closed-form expressions of the STF correlation properties. Based on the developed theoretical reference model, a deterministic simulation model is then proposed and its 3-D STF correlation properties are also investigated by providing closed-form expressions. It is shown that the correlation properties of the simulation model fit those of the reference model very well when the parameters of the simulation model are determined by using the Lp-norm method (LPNM).
