... MSE optimal kernel for the family of locally stationary processes {x Q (t)} and the MSE for the kernel optimized for every (α, β) ∈ Q. The kernel function H x Q −opt works remarkably well for ... which the optimal kernel function is similar to the optimal kernel function for {x( t)}. In this paper, we prove that the MSE optimal kernel function for any parameterized famil...
