This European Telecommunication Standard (ETS) describes the framing structure, channel coding and modulation (denoted "the System" for the purposes of this ETS) for a digital multi-program television distribution by Microwave Multipoint Distribution Systems (MMDS) operating below 10 GHz. The aim of this ETS is to present a harmonized transmission standard for cable, satellite and MMDS, based on the MPEG-2 System Layer ISO/IEC 13818-1 [1], with the addition of appropriate Forward Error Correction (FEC) technique. This System follows the modulation/channel coding system for digital multi-program television by cable (see ETS 300 429 in the bibliography) and is based on Quadrature Amplitude Modulation (QAM) with 16, 32, and 64 constellation points.
