摘要

提出了一种用于MPEG-2视频传输的源信道联合编码(JSCC)方法。基于当前信道状态，该JSCC方法找到最佳的信源和信道码率分布。由于源码的误码敏感性不同，在信道传输过程中，我们采用所谓的速率兼容穿刺卷积(RCPC)信道编码器对源码进行不等错保护(UEP)，以达到有效的保护效果。仿真表明，在相同信道状态和总比特率的条件下，与等错误保护(EEP)编码相比，我们的方法提供了最小的MPEG-2视频整体失真。

A model-driven joint source and channel coder for MPEG-2 video transmission

This paper proposes a joint source and channel coding (JSCC) method for MPEG-2 video transmission. Based on the current channel status, this JSCC method finds the best source and channel code rate distribution. Due to the different bit error sensitivity of the source code, we apply unequal error protection (UEP) for the source bits by using so-called rate compatible punctured convolution (RCPC) channel coder for efficient protection during channel transmission. In the simulations, we illustrate that under the conditions of the same channel status and total bit rate, our method provides the minimal overall distortion of the MPEG-2 video compared to the equal error protection (EEP) coding.
