摘要
DVB-S2作为“第二代”卫星广播传输标准,在传输效率、系统容量、可扩展性等方面的性能指标有显著提高,同时很好地兼顾了可实现性。本文重点介绍了DVB-S2系统中的三项核心技术:自适应编码调制(ACM)、输入适配与新的前向纠错编码技术。
Being the standard of the second generation satellite broadcasting transmission, DVB-S2 advances much in performance guide line such as transmission efficiency, system capacity and flexibility, moreover in feasibility. This article mainly introduces three kernel technics. Adaptive Coding and Modulation(ACM) , Input Adaptation and a new method of Forward Errnr Cnrrection.
