Abstract
For the purpose of reducing the effect of non-line-of-sight (NLOS) error that inhibits accurate location of mobile stations (MS), a novel approach based on the method of Joint Variance Matching Algorithm (JVMA) [1] is presented in our research. In order to improve location accuracy, scattering models are used to classify propagation environments and model the NLOS error effect to be incorporated into a location algorithm. By matching the statistics of the measured time-of-arrivals (TOAs) of several multipath arrivals with those produced by the scattering models, the location estimation of the MS can be obtained.
