Abstract

We investigate the noise power gain (NPG) as a measure of error for transversal estimators. The error upper bound (EUB) and lower one (ELB) are specified via NPG for the most general p-shift linear time-variant transversal estimator intended for filtering (p = 0), prediction (p 0), and smoothing (p K-state space signal models with M states measured. A fast iterative algorithm for NPG of the unbiased FIR estimator is provided along. Examples of applications are considered employing the two-state polynomial space model.
