The study will analyze correlation characteristics, Power Spectral Density (PSD) property and the histogram distribution of time-hopping intervals, following the established methodology. We aim to assess the effectiveness of this method in pulse position detection, comparing it with alternative approaches under various Signal-to-Noise Ratio (SNR) conditions. The simulations shows that compared with other similar scheme, the SITs given by the CC-based method can obtain better correlation performance and detection performance in the receiver,enTime-Hopping, Slot Index Table, Pseudolite Positioning Systems, GNSS, Congruence Codes.Thesis
