A Support Vector Data Description Approach to NLOS Identification in UWB Positioning

<table>The ROC curves for the LSSVM and SVDD. For LSSVM, both LOS and NLOS signals are needed for training, and the number of each of them is 510. For SVDD, only LOS signals are needed for training, and the number of available LOS signals is 510.</table>
