| 摘要: |
| 在数字通信系统中，发送的数据序列中的比特往往具有不等的重要性。为了寻求更可靠的信息传输，人们提出了一些不等错误保护（UEP）编码方案。本文介绍了一种通过删截卷积码（CC）实现UEP编码的方案，并通过仿真分析了该UEP编码的性能。仿真结果表明，运用删截卷积码实现的UEP编码能获得较好的性能。 |

| () |
| Abstract: |
| In many digital communication systems, the bits of the transmitted data sequence do not have equal significance. To seek more reliable information transmission, some UEP coding schemes have been devised. We introduce an unequal error protection coding scheme with punctured convolutional codes, and study the performance of introduced UEP coding scheme by simulations. The simulation results show that such UEP coding scheme may achieve improved performance. |
