摘要:
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.
