Abstract

A positioning method includes: generating a plurality of digital audio broadcasting (DAB) signals in a plurality of transmitters, each of the plurality of DAB signals including a series of transmission frames and each transmission frame including a synchronization channel (SC), a fast information channel (FIC) and a main service channel (MSC); transmitting the plurality of DAB signals such that the SC has a first power and each of the FIC and the MSC has a second power lower than the first power; measuring receiving times of the plurality of DAB signals in a mobile terminal; and determining a location of the mobile terminal using the receiving times.
