A UWB positioning system which performs NLOS identification and TOA-based location estimation is described. For NLOS identification, we consider both a simple variance test, and a more complex non-parametric identification test. The ranging technique is based on TOA estimation, where the nodes can adopt a two-way ranging scheme in the absence of a common clock. From the NLOS identification and range estimation steps, an approximate MLE technique is employed for the node positioning.
