scope:

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.

The System FEC is designed to improve Bit Error Ratio (BER) from 10-4 to a range, 10-10 to 10-11, ensuring "Quasi Error Free" (QEF) operation with approximately one uncorrected error event per transmission hour.
