摘要：
In order to prevent an incorrect synchronization between a received code-modulated signal and an available replica code, partial correlations are performed between a respective subset of samples of the replica code and samples of the received code-modulated signal associated to the respective subset of samples of the replica code at a specific alignment between the received code-modulated signal and the replica code. The results of the partial correlations are then compared to each other, and it may be decided based on this comparison whether the replica code corresponds to a code employed for code-modulating the received code-modulated signal.
