WebAbstract—This contribution considers the non-Bayesian Cramér-Rao bound (CRB) related to parameter estimation from a linearly modulated signal observed in additive white Gaussian noise. We compare the exact CRB expression for coded modula-tion with two ad hoc CRB (ACRB) expressions; the ﬁrst ACRB is http://www.dauwels.com/Papers/BCRB.pdf
