Abstract
A method for localizing a mobile device in a physical space based on radio signals received from transmitters in the physical space includes a step of transforming a received signal strength vector to produce a transformed received signal strength vector. Sequence based localization is performed on the transformed RSS vector with a different ideal sequence centroid table.
