摘要
主要介绍了Turbo码在DVB_T系统中的应用。首先对DVB-T系统中信道编码的基本原理进行了简单介绍,并将Turbo码技术引入到DVB-T系统的纠错机制中,最后利用仿真系统对改进后的纠错机制进行研究。仿真结果表明,将信道编码更换为Turbo码的新DVB-T系统具有比原系统更好的纠错性能。
This article mainly introduces the application of Turbo codes in the DVB-T system. Firstly, we simply introduces the principle of channel coding of DVB-T, inserts the Turbo codes technology into the error-correcting system of DVB-T. Finally the performance is investigated between standard DVB-T and improved DVB-T through simulation. The simulation result shows that the errorcorrecting performance of improved DVB-T is better than standard DVB-T.
