摘要
介绍了欧洲第二代有线数字电视标准DVB-C2在DVB-C基础上所进行的改进,概述了DVB-C2系统原理及应用特性。DVB-C2采用OFDM技术结合先进的LDPC编码以及时域、频域二维交织技术,提高了系统的频带利用率和易用性,并将极大地扩展广播电视网络的服务功能。
In this paper, the improvement of DVB-C2 based on DVB-C is introduced and the system characteristics of DVB-C2 are summarized. DVB-C2 is the second generation of European cable DTV, which applies advanced technologies like OFDM, LDPC and a two-dimensional interleaving technique in both frequency and time domain. With a high degree of flexibility and spectrum efficiency, this new DVB transmission system will extend the service function of broadcasting networks immensely.
