ABSTRACT:
The invention relates to a method for synchronizing a receiver (1) with a transmitted code-modulated spread spectrum signal. The method uses at least one reference code (r(x)), which corresponds to a code used in the modulation. The frequency shift of the transmitted signal and the code phase of the code used in the modulation are determined in the method.
