We investigate the physical layer performance of a DVB‐S2 system with a digital optical feeder link. We consider three scenarios depending on how the DVB‐S2 modulator functionalities are distributed between the optical gateway and the satellite. Our main objective is to specify the residual bit error rate of the optical channel error correction scheme in order to ensure a quasierror free link to the users. To that end, we provide theoretical models and/or simulations results. In two scenarios, our results show that a residual bit error rate of 10−4 (assuming equally distributed errors) gives end‐to‐end physical layer performance compliant with the DVB‐S2 standard. This specification is much higher than typical values in practical systems.

具有数字光馈线链接的DVB-S2系统的性能评估

我们研究了具有数字光馈线链路的DVB-S2系统的物理层性能。我们根据光网关和卫星之间DVB-S2调制器功能的分布情况来考虑三种情况。我们的主要目标是指定光通道纠错方案的残留误码率,以确保与用户的准无误链接。为此,我们提供了理论模型和/或仿真结果。在两种情况下,我们的结果表明,残差的误码率为10 -4(假设平均分布的错误)可提供符合DVB-S2标准的端到端物理层性能。该规范比实际系统中的典型值高得多。
