Title: METHOD AND APPARATUS FOR RECEIVING TD-ALTBOC SIGNAL
Abstract:
Disclosed are a method and apparatus for receiving a TD-AltBOC signal, belonging to the field of global satellite navigation. The method of the invention includes the following steps: converting a TD-AltBOC radio frequency signal into an intermediate-frequency and band-pass filtered signal and sampling same, and a local carrier being used for stripping a sampled signal carrier so as to obtain a sampled baseband signal; correlating a local waveform to the sampled baseband signal chip-by-chip in a time division manner; performing data demodulation according to a related output signal, and acquiring a carrier phase deviation estimation value and a code phase deviation estimation value according to the related output signal; generating the local waveform according to the code phase deviation estimation value; and generating the local carrier according to the carrier phase deviation estimation value. The present invention also achieves a receiving apparatus for a TD-AltBOC signal. The technical solution of the present invention is easy to implement, the receiving complexity is reduced, and hardware resources are saved.
