Description

A linear precoding in time-varying multi-input multi-output(MIMO) channels is considered. We propose a channel extrapolation method for a linear precoding. A pecuriality of this method is to modify the pilot aided channel estimation for single-input single-output (SISO) systems and predict channel fading envelope using the polynomial extrapolation. The applicability of the proposed method is demonstrated by computer simulations.
