Patent ID: 7336696

Claim:
An apparatus supporting an acquisition of a received code modulated signal by determining the correlation between said received code modulated signal and an available replica code sequence at different code phases relative to each other, said apparatus comprising: a first acquisition engine for selecting code phases which are good candidates for being the code phase at which a received code modulated signal and said available replica code sequence have the highest correlation, and for outputting information on each selected code phase; and a second acquisition engine for receiving information on selected code phases from said first acquisition engine and for performing a refined comparison between a received code modulated signal and an available replica code sequence for each selected code phase on which information is received, wherein said first acquisition engine is adapted to select said code phases as part of a respectively selected set of a code phase and a frequency employed for a frequency compensation of said received code modulated signal, said first acquisition engine providing information on each selected set, and wherein said second acquisition engine is adapted to perform said refined comparison between a received code modulated signal and an available replica code sequence for the code phase of each set on which information is received and with a frequency compensation of said received code modulated signal using the frequency belonging to the respective set.
