Abstract

3G FDD W-CDMA initial synchronization follows a 3-step procedure to find a primary scrambling code while locating the frame boundary. In step 2, simplified coherent combining of secondary codes has been introduced for group and slot offset identification. The proposed method shows significant performance improvement against frequency offset. The simulation results show that there is approximately 3 dB performance improvement compared to conventional coherent integration for 6 kHz carrier offset while the other results follow almost the same values as those of conventional coherent integration
