A compact Cramer-Rao bound expression for parametric estimation of superimposed signals
Sze Fong Yau, Yoram Bresler · IEEE Transactions on Signal Processing · 1992
The problem of parameter estimation of superimposed signals in white Gaussian noise is considered. Closed-form expressions of the Cramer-Rao bound for real or complex signals with vector parameters are derived, extending recent results by P. Stoica and A. Nehorai (1989).>
