DVB-C

Standard DVB-C is the application of the standard DVB to the rope drives.

This standard takes account of the characteristics of a transmission on cable:

  1. the band available is reduced: 8 MHz, one thus will need an important spectral effectiveness,
  2. the signal is protected and amplified, the signal report/ratio with noise is good,
  3. the disturbances must with the echoes caused by a bad adaptation of the catch user.

To obtain a good spectral effectiveness, one uses a modulation QAM -64 associated with a linear equalizer or DFE (Decision Egalizer Feedback) based on the criterion of the zero-sustained pressure in order to cancel the intersymbol interference.

Standard DVB-C is not compatible with the standard DVB-T.
