Figure 5From: On the maximum likelihood estimation of the ToA under an imperfect path loss exponentRMSE of the estimated distance as a function of the PLE error. RMSE of the ML distance estimate as a function of the PLE error δ γ for several values of the SNR, with γ0=1.7, c τ0=4 m, β ̄ =3.1007×1 0 9 Hz, sampling time = 0.01 ps, and NR=6,000 independent runs.Back to article page
