In this paper, we come up with a robust carrier phase synchronization scheme in DVB-S2x Annex E SF mode format 2 for VL SNR channel. Unlike DVBS2 standard, DVB-S2x standard can support VL SNR condition by around -10 dB which is useful for low profile antenna and heavy rain channel condition. The proposed scheme is applicable to reduce the FER performance degradation which is caused by inaccurate estimation. By means of computer simulations, we can show that there were practically much closer approaches over the ideal AWGN channel for the proposed scheme in terms of FER performance.
