Abstract:
1. A method for supporting a correlation based tracking of a code modulated signal received at a receiver, wherein samples of said received signal and samples of at least one available replica code sequence are aligned to each other and wherein positions of said samples in said received signal and in said at least one replica code sequence are grouped, each group comprising all positions at which the composition of values of the samples of all of said at least one replica code sequence is similar, said method comprising: combining the values of the samples of said received signal which are associated by their positions to a respective group separately for each group to obtain a respective intermediate result; and determining a correlation value for each of said at least one replica code sequence by combining obtained intermediate results for all groups separately for each of said at least one replica sequence taking into account the values of the samples of said at least one replica sequence in the respective group.
