摘要

The new DVB-C2 physical layer architecture composing state of the art modulation and channel coding techniques provides superior transmission capabilities compared to existing systems such as DVB-C and DOCSIS. Results of simulations performing signal transmissions under realistic cable channel conditions indicate an increase of some 7 dB in terms of robustness and of up to more than 60 % in terms of spectral efficiency. A broad roll-out of DVB-C2 in cable networks, however, will not only increase the capacity of the networks significantly, it will also provide new operational opportunities for MSOs due to the high degree of flexibility supported. Incorporating the DVB-C2 PHY in DOCSIS and using it for DOCSIS downstream transmission will result in a flexible and efficient broadband communications system.
