| Abstract: |
| Improving the accuracy of location positioning system in cellular network is the key for location based services to be widely applied in code division muitiple access(CDMA) systems. In this paper, focusing on the main researches on cellular location positioning system, such as basic location algorithm, non-line-of-sight (NLOS) propagation mitigation algorithm, multi-path and multi-access interruption mitigation algorithm, data fusion location positioning algorithm, algorithms for improving location positioning accuracy are analysed and discussed.New opinions are presented, and the future of location positioning research is reviewed. |
