Abstract: Non-line-of-sight (NLOS) errors which derived from the blocking of direct paths have been considered as the dominant problem in the mobile position estimation. Therefore, this study presented a study on the residual weighting algorithm (RWGH). First, the drawback of the traditional RWGH was investigated and then a base station selection strategy was proved to be effective. Moreover, the weight determination also plays an important role in the RWGH and the conventional reciprocal weight performs poor when the number of Line-of-sight (LOS) base station is small. Thus, some new weight computing schemes were proposed and compared, resulting in better performance at the case with few LOS base stations. The proposed algorithm was tested by computer simulations and the result showed better performance and smaller complexity compared with the conventional one.
