NLOS mitigation in Indoor UWB Location Networks using Linear Programming

Obstacle LOS Link • In the context of cellular communications, it has been shown that the NLOS bias errors in the range estimates lead to large errors in the computation of a node’s location. • The literature on the NLOS problem typically falls in two categories: NLOS identification and NLOS mitigation. • The former deals with the problem of distinguishing between LOS and NLOS range estimates, whereas the latter typically deals with the reduction of the adverse impact of NLOS range errors on the accuracy of location-estimates, assuming the NLOS range estimates have been identified.
