Abstract:
A method for predicting precoding matrix (PM) in a MIMO System includes the steps of: obtaining a present PM based on a present transmission; fitting the present PM and previous PMs with a predefined model; and determining a forthcoming PM which is expected to be used in the next transmission based on the fitting.
