Title:
衛星信号からナビゲーションビットを復調するためのシステム
Document Type and Number:
Japanese Patent JP5230675
Kind Code:
B2
Abstract:
A signal processing system for demodulating navigation bits from a satellite signal is disclosed herein. The signal processing system includes a digital baseband processor for determining a boundary between two navigation bits in the navigation bits according to a first plurality of coarse acquisition (C/A) codes captured from the satellite signals, storing the first plurality of C/A codes, and demodulating a second plurality of C/A codes captured after determining the boundary to recover a first series of the navigation bits. The signal processing system further includes a complementary demodulating unit coupled to the digital baseband processor for demodulating the first plurality of C/A codes to recover a second series of the navigation bits.
