Abstract :
An efficient algorithm used to detect and mitigate NLOS propagation error is proposed in this paper. The method reorganizes NLOS receivers by selecting weights matrix, and then refreshes their measurements to mitigate the effects of NLOS propagation. Comparing with CRLB and from the results of simulation, we can find that this algorithm is simple and has high estimation accuracy.
