Localization using Ultra Wide Band (UWB) signals can show large errors. Due to Non-Line-of-Sight (NLOS) propagation and low signal to nosie ratio (SNR), it is possible to expect that the first arriving path and the strongest path are not equal to each other. This problem can be modeled as a multihypothesis problem. We base our decision on matched subspace detectors. The case where we deal both with Time of Arrivals (TOA) and Angle of Arrivals (AOA) is also studied.
