Turbo码在DVB-S系统中的应用研究

Research on Application of Turbo in DVB-S System

Turbo码以其优异的纠错性能被应用于多领域。为了提高DVB-S系统的性能,文中将Turbo码引入了DVB-S系统。利用仿真系统,引入Turbo码与传统的系统进行了性能比较。针对两种不同译码算法,给出了两种系统在不同信噪比下的误码率曲线。实验结果表明,引入Turbo码后系统的性能有明显的提高。

Turbo code is applied in many fields for its excellent performance in correction. Turbo-code is introduced to the DVB-S system to improve its performance. A comparison in performance with the conventional system through simulation is made, and the BERs under different SNR by different decoding algorithms are presented. Experiment results show that Turbo-based DVB-S has a significant improvement in performance.
