Abstract:
1. A method for supporting an acquisition of a code modulated signal received at a receiver, wherein at least a first set of correlation results for correlations between said code modulated signal and a first replica code with different code phases and a second set of correlation results for correlations between said code modulated signal and a second replica code with different code phases are available, said second replica code different from said first replica code, said method comprising: combining results from said first set of correlation results and from said second set of correlation results, wherein correlation results used in said combination are selected based on information on a relative difference between a correct code phase for said first replica code and a correct code phase for said second replica code; and determining based on said combination whether at least one of said first set of correlation results and said second set of correlation results comprises a correlation result representing said correct code phase for said first replica code or said second replica code, respectively.
