This acquisition method is provided for acquiring a satellite signal from a navigation satellite, the satellite signal contains an own cyclic pseudo-random identification code of the satellite. The acquisition method comprises generating a local code replicating the identification code, and performing a ...
In the global positioning system (GPS), code acquisition involves searching all possible code-phase candidates for the existence of satellites. Although code-phase search using a matched filter (MF) is efficient for one satellite, computational complexity increases if numerous satellites have to be se...
