Review of Parametric Radio channel prediction schemes for MIMO system

To ensure reliable communication and improve performance of a wireless communication system, it is required for the transmitter and receiver to have fair knowledge about the channel state information (CSI). Analysis of the basic channel prediction schemes like Parametric Radio channel model, Autoregressive model based prediction and Bandlimited basis expansion is done in this paper. Subspace based channel estimation techniques used by the parametric radio channel model for channel estimation is discussed in detail and a comparison of the techniques is also given in this paper work.
