Zusammenfassung:	A positioning method using digital audio broadcasting is provided to reduce the number of transmitters by transmitting DAB(Digital Audio Broadcasting) and TDMB(Terrestrial Digital Multimedia Broadcasting) signals at different powers for respective channels of a transmission frame. A transmission frame multiplexer(210) receives FIC(Fast Information Channel) data and MSC(Main Service Channel) data from the outside. An FIC/MSC symbol generator(220) receives the FIC and MSC data and generates a first symbol. A synchronous channel symbol generator(240) generates a second symbol corresponding to the synchronous channel information. A first gain block(260) amplifies the power of the second symbol by a first gain ratio. An OFDM signal generator(230) receives the first and second symbols to generate an OFDM signal. A TTI signal generator(250) adds TTI(Transmitter Identification Information) signals to the OFDM(Orthogonal Frequency Division Multiplexing) signals to generate a DAB signal.
