In this paper, a new class of hybrid lower bounds on the meansquare-error of estimators is proposed. Derivation of the proposed class is performed by applying an integral transform on the centered likelihood-ratio (CLR) function. It is shown that the hybrid Cramér-Rao and Barankin bounds are the limits of convergent sequences of bounds, which are obtained from the proposed class using specific sequences of integral transform kernels. A new hybrid bound is derived from the proposed class using a… CONTINUE READING
