• Since FTN signaling uses greater symbol rate than Nyquist rate, the FTN signaling offers higher spectral efficiency than that of Nyquist signaling. However, ISI is derived from the non-orthogonality of FTN signaling. The ISI leads to an increase of the envelope fluctuations. Consequently, high PAPR occurs in the FTN signaling. In the satellite communication link, the high PAPR causes performance limitation because of non-linear amplification effects. Therefore, to adopt FTN signaling, PAPR reduction scheme is required in satellite digital broadcasting system. Furthermore, for various reasons such as security of pay-contents, data masking can be efficiently used for digital broadcasting system. Therefore, this paper proposes joint masking and PAPR reduction technique based on scrambling signal frame for the broadcasting system based on DVB-S2 standard with FTN signaling.
