Webthan the CRB is the Barankin bound [4], which is the greatest lower bound on the variance of any unbiased estimator. Unfortunately, most estimators exhibit an unknown bias when the SNR decreases. Conse-quently, the Barankin bound and, more generally, deterministic bounds are not fully appropriate for investigating the ultimate performances WebApr 3, 1990 · The bound is applicable to biased estimates of vector-valued functions of a vector-valued parameter. Termed the hybrid Bhattacharrya-Barankin bound, it can be written as the sum of the mth-order Bhattacharrya bound and a nonnegative correction term dependent on a set of r so-called test points.
