Abstract

A NLOS identification algorithm based on rician K-factor hypothesis test was proposed to mitigate position location bias caused by NLOS propagation in MIMO-OFDM system. A multi-antenna rician K-factor estimation method was derived from the correlation difference of deterministic and diffuse component between antennas. A rician K-factor decision model was established according to signal propagation environment. The identification result was derived from the decision model with the estimated K-factor. Simulation results showed that the proposed algorithm could achieve good identification performance even when K was small and had a good robustness to antenna configuration and scattering distribution.
