Abstract
The invention relates to a method, a processing unit and a system for determining the correlation between consecutive sets of samples of a received, code modulated signal and replica samples. In order to reduce the computational load, the positions of samples in said replica code sequence are grouped, each of these positions and a predetermined number of respective subsequent positions forming a subgroup and each group comprising the respective first position of all subgroups with positions associated with a similar composition of consecutive replica samples. The method combines those values of samples of the first set of samples, which are associated by their position to a respective group, separately for each group to obtain a respective preliminary result. Determining a correlation value for each of the sets of samples then comprises combining the obtained preliminary results for all groups separately for each of the sets of samples.
