| description | A positioning method of a circular polarization wave which is able to apply to TD-SCDMA network is provided to realize exact positioning of a mobile terminal in an indoor, thereby performing the real ubiquitous positioning. A positioning method of a circular polarization wave which is able to apply to TD-SCDMA network includes the steps: receiving signal information and positioning request signal from a mobile terminal by a position server(S2); initializing signal strength by using the signal information and the positioning request signal received from the mobile terminal(S4); performing power correction using the signal information by the position server(S6); searching lattice data approaching within certain range using a maximum likelihood principle by the position server(S8); distributing all weighted value using the lattice data(S10); and calculating a location coordinate value by multiplying the coordinate value of the lattice data and the distributed weighted value(S12). |
