| Abstract: | The problem of determining the positions of speakers in an array given noisy measurements of inter-speaker ranges is considered. A closed-form position estimator which minimizes a weighted equation error norm is presented. The information inequality is used to bound the position estimate mean square error and to gauge the accuracy of the closedform estimator, which is shown to be nearly efficient. | ||
