ABSTRACT:
A method for supporting a determination of the correlation between at least one received code modulated signal and at least one available replica code is shown. In order to reduce the total memory size required for such correlations, the method comprises storing signal samples of the at least one received code modulated signal with a first rate in a memory. The stored signal samples are then read with a second rate from the memory for determining a correlation between the read signal samples and samples of the at least one available replica code, wherein the second rate is higher than said first rate. The disclosure relates equally to a corresponding electronic device, to a chip for such an electronic device, to a system comprising such an electronic device and to a corresponding software product.
