Abstract :
Mobile positioning is made difficult by contamination of measured time of arrival (TOA) data caused by NLOS propagation. In this paper, a adaptive NLOS error mitigation algorithm is proposed without prior NLOS error distribution. Simulations in difference channel environments show that the performance of our algorithm comes close to meeting Cramer Rao lower bound (CRLB).
