In order to make wise use of network resources, this paper proposes a video transmission scheme in which the source coding distortion and transmission distortion to the video quality are formulated and fountain code is used as the channel coding for unequal protection in scalable video transmission....
文章简要概括:文中提出了一种神经纠错和信源修剪码(NECST:Neural Error Correcting and Source Trimming),即通过端到端的方式去学习联合编码和解码。 针对于如何将图像数据编码为比特流,使得其能够在带噪通信信道中进行可靠地传输这一问题,香农的结论是对于一个无记忆信道,当图像大小趋于无穷时,最好地方法是将信源编...
We introduce the concept of joint source coding, channel coding, and secrecy. In particular, we propose two practical joint schemes: the first one is based on error-correcting randomized arithmetic codes, while the second one employs turbo codes with com
Recently joint source-channel coding and decoding (JSCC/D) are greatly attracted in wireless senor networks (WSN) since they are inspired by 5G although they have been classical topics since 1980. In these techniques JSCC/D based on double Protograph LDPC (DP-LDPC) Codes has become new objecti...

We consider the problem of joint source and channel coding of structured data such as natural language over a noisy channel. The typical approach to this problem in both theory and practice involves performing source coding to first compress the text and then channel coding to add robustness for...
