Fig. 11From: Cramer-Rao bounds in the estimation of time of arrival in fading channelsCRB of k0 as a function of the roll-off factor of the shaping pulse. Results are provided for different values of the dispersed SNR when the LOS power level is 0 dB higher than the dispersed signal and an ICD source (α=0). 50 channel vector estimates are available. The sampling rate set to twice the chip rate, delay spread set to 2 T c , angular spread set to 5°, and four sensors. a Left: bearing =0°. b Right: bearing =45°Back to article page
