Abstract :
We consider the statistical properties of nonparametric transfer function estimates formed via the weighted sum of empirical transfer function estimates. In the case that the system input is considered deterministic, we show that the weighting corresponding to the classical averaged periodogram estimate is optimal. A similar asymptotic result is derived for the case where the input is considered stochastic.
