Figure 6From: On the maximum likelihood estimation of the ToA under an imperfect path loss exponentBias (top) and RMSE (bottom) of the estimated distance as a function of the SNR. LOS transmission with γ0=1.7, δ γ =±0.2, σ dB 2 =1.6, c τ0=4 m, β ̄ =3.1007×1 0 9 Hz, sampling time = 0.01 ps, and NR=6,000 independent runs. Note that the Monte Carlo approximation of the RMSE is independent of the sign of δ γ .Back to article page
