Abstract :
A minimax estimator of the mean of x~N(θ, Rn) is evaluated, where Rn is Toeplitz. The problem can be viewed as estimating a signal θ that has been corrupted by additive wide-sense stationary noise. The evaluation is carried out using a frequency-domain approach that yields advantages in design and analysis. In particular, counterintuitive performance of an entire class of minimax forms is discovered when R n is not diagonal. A numerical example is presented to demonstrate the performance
