Abstract: Methods and systems for DVB-C2 are disclosed and may include receiving data encoded utilizing variable encoding, variable modulation and outer codes via a physical layer matched to a desired quality of service. An error probability may be determined for said received data and retransmission of portions of said data with error probability above an error threshold may be requested. The variable modulation may include single carrier modulation, orthogonal frequency division modulation, synchronous code division multiple access, and/or from 256 QAM to 2048 QAM or greater. The variable encoding may include forward error correction code, which may include low density parity check code.
Abstract translation: 公开了DVB-C2的方法和系统，并且可以包括通过与期望的服务质量匹配的物理层来接收利用可变编码，可变调制和外部码编码的数据。 可以针对所述接收的数据确定错误概率，并且可以请求误差概率高于误差阈值的所述数据的部分的重传。 可变调制可以包括单载波调制，正交频分调制，同步码分多址，和/或从256QAM到2048QAM或更大。 可变编码可以包括前向纠错码，其可以包括低密度奇偶校验码。
