Comparison of Autocorrelation and Cross-Correlation Methods for Signal-SelectiveTDOA Estimation

摘要

Two recently proposed algorithms for signal-selective time-difference-of-arrivalestimation 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 the MSE is independent of the distance between sensors for both algorithms. (AN).
