摘要:
通过Turbo预编码思想与不等差错保护技术的结合,以达到对不同重要性信息的不等保护.所设计的Turbo预编码方案,以简单的线性分组码为外码(预编码器),以Turbo码为内码构成的串行级联码.针对这种预编码方案研究了新的外码SISO迭代译码算法.最后,对1/3码率的Turbo预编码系统按外码译码方式的不同进行了仿真,并与1/2、1/3码率的Turbo码作性能比较.结果表明,本方案不仅使Turbo码的性能得到了有效的提高,也实现了对不同信息的不等差错保护.而且,编译码思路简单可行.
Abstract:
The combination of precoded Tarbo thoughts and unequal error protection techndogy,helps toacheive unequal protection for information with different importance. The precoded turbo coding scheme de-signed in this paper consists of the simple linear block code as the outer code ( precoder) and the Turbo codeas the inner code. They make up the serial concatenated codes.According to this precoding scheme,this pa-per researches a new outer code SISO iterative decoding algorithm. At last,1/3 rate of the precoded Turbosystem has been simulated according to the decoding algorithms of outer code，and has been compared with theperformance of 1/2 and 1/3 rate Turbo code.The results show that this scheme not only improves the perform-ance of Turbo code effectively,it also realizes unequal error protection for different informations. And the cod-ing and decoding ideas are simple and feasible.
