Comparison of autocorrelation and cross-correlation methods for signal-selective TDOA estimation
William A. Gardner, Chad M. Spooner · IEEE Transactions on Signal Processing · 1992
Two algorithms for signal-selective time-difference-of-arrival estimation are compared in terms of their implementation and their mean-squared errors (MSEs). A tradeoff between ease of implementation and MSE performance is shown to exist. It is shown that MSE is independent of the distance between sensors for both algorithms.>
