Abstract
An apparatus for transforming a signal strength of a wireless positioning system is provided. The apparatus is adapted for eliminating the difference of signal strengths between different mobile communication apparatuses or different environments. The apparatus includes a location estimation circuit. The location estimation circuit is adapted to obtain a possible coordinate by calculating a first signal strength distribution received by a mobile communication apparatus. The possible coordinate and the first signal strength distribution are taken as training data for training a transforming module with an approximation algorithm. Accordingly, the present invention adopts a positive correlation index and the approximation algorithm for automatically training a transforming module for the mobile communication apparatus without using the information of chip model and location of mobile communication apparatus.
