| 摘 要： | 数字视频广播DVB（Digital Video Broadcasting）标准是欧洲数字电视的传输标准，它包括数字信源压缩编码、节目数据流的统计复用、信道纠错编码、调制等数字传输链路各相关环节所采用的技术及接口标准。本文在介绍DVB技术原理的基础上，深入探讨了DVB系统的构成及调制、解调原理，并在Systemview下对该系统进行了完整仿真。通过信号观察窗对比信号波形发现，输入输出基本一致，说明该系统在通常信噪比条件下可以满足可靠传输的基本要求，达到了预期目的，证明了系统的可靠性。

| Abstract: | Digital Video Broadcasting(DVB) standard is the transmission standard of European digital television, which includes digital source compressed coding, program data stream multiplexing, channel error-correcting coding, modulation, and other technology and interface standards used by the relevant links in digital transmission link. Based on the DVB technical principle, this article discussed the structure of the DVB system and the principle of modulation and demodulation and completely simulated the system by... |
