摘要
Any regular stationary random processes can be represented as the sum of a purely indeterministic process and a deterministic one, This paper considers the achievable accuracy in the joint estimation of the parameters of these two components, from a single observed realization of the process, An exact form of the Cramer-Rao Bound (CRB) is derived, as well as a conditional CRB, The relationships between these bounds, and their relations to the previously derived asymptotic bound, are explored by analysis and numerical examples.
