| 摘 要： | INTRODUCTION The second generation satellite digital video broadcasting standard (ETSI, 2004) has come out recently. Compared with the previous satellite stan-dard DVB-S (ETSI, 2003), DVB-S2 has more ad-vantages, such as the 30% increase in channel capac-ity, the more reliable performance, and the more ef-ficient usage of transponders. The DVB-S2 standard has been designed having in mind the peculiarities of the satellite channel, particularly the link fading im-pairments and the …

| Abstract: | This paper details on the design of DVB-S2 receivers which is compliant with the broadcasting mode. Special at-tention is paid to the specific receiver functions necessary to demodulate the received signal. To show the system performance we consider the design of a complete receiver consisting of timing recovery unit, frame synchronization unit, frequency recovery unit and phase recovery unit. The system is easier to hardware implementation comparing with that provided in (ETSI, 2005; Sun et al., 2004). After the performance of the algorithms is analyzed and a quantitative result is given, this allows us to draw conclusions concerning the achievable system performance under realistic complexity assumptions. |
