- 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.
