卷积码中运用交织器实现不等错误保护

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。分析了卷积码潜在的UEP性能,并通过量化、交织器以及最佳卷积码(CC)的综合设计,在CC的基础上实现UEP。仿真结果表明,在卷积码的基础上运用交织器的编码器设计方案,可以获得较好的交织增益,从而改善编码器的性能。

Unequal Error Protection in Convolutional Codes with Interleaver

In many digital communication systems, the bits of the data sequence transmitted do not have equal significance. To seek more reliable information transmission, some UEP coding schemes have been devised. We investigate the potential of UEP capability embedded in CC, then, by deliberately combined designing of the quantizer, interleaver and the best CC, we implement the UEP in CC. By simulation results, the proposed scheme can attain good interleaver gains, thus improve the performance of CC.
