摘要 由于Turbo码能得到较大的编码增益,因此许多低信噪比通信系统中都选择了Turbo作为信道编码。本文在简要介绍Turbo码的编译码原理的基础上,对Turbo码在通信系统中的应用进行了仿真,重点分析分析了译码方法、译码迭代次数、码率对Turbo性能的影响。 Due to the excellent performance of error correcting, Turbo codes are chosen for the channel coding algorithm for low-SNR communication system o This paper present the basal thoery of coding and decoding algorithm brielfly. In simulation,the effect of decoding algorithm, rate and iteration number is analysis on the performance of Turbo codes.
