摘要：

We derive expressions for the Cramer-Rao Bound (CRB) for the estimates of the parameters of a deterministic signal observed in additive and multiplicative noise which may be i.i.d. non-Gaussian or colored Gaussian. General expressions for the CRB are derived, and are then applied to the specific case of polynomial phase signals for which closed-form expressions are obtained under certain assumptions, We also develop bounds on the CRB; these bounds are tight at low SNR.
