Closed-form cramér-rao lower bounds of the Ricean K-factor estimates from I/Q data


Closed-form CRLBs are derived for estimates of the Ricean K-factor from I/Q data. Indeed, the CRLBs evaluate effectively the estimators and indicate the best approach to adopt. The CRLBs are derived in two cases. In the first case, only the Ricean K-factor is assumed unknown, while in the second case the Line-Of-Sight (LOS) phase, Angle of Arrival (AoA… (More)
