摘要
分析了DVB-S2相对DVB-S的新特性和发展现状,提出了一种基于TDQR-C005F的DVB-S/S2信号接收参数的搜索方案。重点对宽带信号载波的中心频率、带宽参数的搜索技术以及信号频道的符码率、编码码率和导频参数的三级搜索技术进行了算法和实现研究。与传统算法相比,算法和系统快速有效地解决了对DVB-S/S2突发信号的检测识别。
New features and development status of DVB-S2 are analyzed compared to DVB-S, a novel search program of the DVB-S2 signal reception parameter based on TDQR-COOSF is proposed. This paper focuses on the search technology of carrier center frequency and bandwidth parameters about the broadband signal, and three-step search technology and implementation of the algorithm concerning parameters of the signal channel including symbol rate, coding rate and pilot frequency. The algorithms and systems can effectively solve the detection and identification requirements of the DVB-S2 burst signal compared to traditional algorithms.
