The present invention, pertaining to the field of wireless communications, discloses a mobile broadcast-based method and apparatus that includes: receiving a mobile broadcast signal; demodulating a location spreading signal inserted in the header of a time slot or a transmission frame of the mobile broadcast signal to acquire navigation message information, and measuring and acquiring location characteristic parameters, wherein the navigation message information includes the identifier of a mobile broadcast station, and the location characteristic parameters correspond to the identifier; and acquiring location data according to the location characteristic parameters and the navigation message information. According to the method and apparatus, a location spreading signal is carried in the header of a time slot or in the header of a transmission frame of the mobile broadcast signal, navigation message information is acquired by demodulating the location spreading signal, and location characteristic parameters are acquired by measurement to acquire location data.

Mobile broadcast-based location determination method and apparatus

Disclosed is a mobile broadcast signal demodulation chip for location. The demodulation chip includes a reception demodulation and module and a measurement module, where the reception and demodulation module is configured to demodulate a spread spectrum signal for positioning inserted in the header of a time slot or in the header of a transmission frame of a received mobile broadcast signal to acquire navigation message information; and the measurement module is configured to measure and acquire location characteristic parameters. The demodulation chip is not only capable of demodulating broadcast data in a mobile broadcast signal, but also capable of demodulating a spread spectrum signal for positioning-inserted in the header of a time slot or in the header of a transmission frame of a received mobile broadcast signal to acquire navigation message information and location characteristic parameters, thereby effectively improving location accuracy.
