Wireless positioning method and device

The invention provides a wireless positioning method and device. The method includes: respectively collecting the receiving signal strength of multiple know reference points at a to-be-measured point; estimating the value space of the to-be-measured point according to the receiving signal strength; dividing the estimated value space into a plurality of equal grids; solving corresponding Pearson product-moment correlation coefficients, determining the minimum Pearson product-moment correlation coefficient rho L, and using the grid of a position corresponding to the rho L as the position space of the to-be-measured point. By the wireless positioning method, high-precision wireless positioning can be achieved through low calculation complexity.
