Fig. 4From: Cramer-Rao bounds in the estimation of time of arrival in fading channelsCRB of the first arriving path k0 for different values of the SNR. Results are provided for different values of the temporal correlation α and different angular spreads for the received signal. The number of sensors is 1 (solid) and 4 (solid bullet). Delay spread set to 5 T c , for 50 channel vector estimates. a Left: angular spread set to 5°. b Right: angular spread set to 10°Back to article page
