Extrapolation estimates a variable's value beyond its initial observation range based on relationships with other variables. Unlike interpolation, extrapolation carries greater uncertainty and risks ...
Abstract: In time division duplexing (TDD) millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, downlink channel state information (CSI) can be obtained from uplink channel ...
Extrapolation scheme combines two half-steps and the full time step to obtain desirable properties. See more details below in `extrapolation_scheme`.
