Accuracy Comparison of LS and Squared-Range LS for Source Localization
2010 (English)In: IEEE Transactions on Signal Processing, ISSN 1053-587X, E-ISSN 1941-0476, Vol. 58, no 2, 916-923 p.Article in journal (Refereed) Published
In this correspondence we compute a closed-form expression for theasymptotic (large-sample) accuracy of the recently proposedsquared-range least-squares (SR-LS) method for source localization. We compare its accuracy to that of the classicalleast-squares (LS) method and show that LS and SR-LS performdifferently in general. We identify geometries where theperformances of the methods are identical but also geometries when thedifference in performance is unbounded.
