Fig. 7From: Cramer-Rao bounds in the estimation of time of arrival in fading channelsCRB of k0 as a function of the number of channel vector estimates K. Results are provided for different values of the temporal correlation coefficient α, SNR =10 dB, and a delay spread of 5 T c . a Left: one sensor. b Right: four sensors and two possible scenarios: uncorrelated sensors case and a low angular spread case (angular spread of 5°)Back to article page
