Requirements for advanced digital cable transmission technologies (Study Group 9)


ITU-T J.381-2012 发布历史

Among the three options described in the introduction, this Recommendation limits the scope to the employed technologies to improve spectral efficiency for downstream and upstream over hybrid fibre/coax (HFC)-based networks. The requirements stated herein are intended to be technology neutral. Furthermore, this Recommendation defines the requirements for advanced digital cable transmission technologies on the physical layer, which includes modulation, channel coding, transmission schemes and frame structure for providing higher spectral efficiency.
