WebJun 19, 2006 · Abstract. The search for an easily computable but tight approximation of the Barankin bound (BB) is important for the prediction of the signal-to-noise ratio (SNR) value where the Cramer-Rao bound ... WebJan 1, 2015 · In most cases, it is extremely difficult to derive an analytical form of the Barankin bound by optimizing with respect to M and the test points {θ j}. In Fig. 2, we plot the Barankin-type bounds for s n (θ) = cos(2π n θ) for M = 10 randomly selected test points. We observe that Barankin-type bound is tighter than the CRB when SNR is small.

WebWe show that, under mild conditions, the Barankin bound (the tightest possible lower bound on the estimator variance) is a lower semi-continuous function ofthe parameter vector. We also show that the RKHS associated with an MVE problem remains unchanged if the observation is replaced by a sufficient statistic.
