While coding has a theoretical basis, it has a practical side as well, an engineering side in which costs and benefits matter. It is safe to say that most of the recent advances in information theory and coding are in the engineering of coding. These thoughts motivate the present text book...

hiding and watermarking, readily map to the source and channel coding problem in digital communications. As such, established concepts from digital communications could be used to solve this problem. In Section 2 we discuss in detail our data hiding approach ...
In this paper, we propose two deep joint source and channel coding (DJSCC) structures with attention modules for the multi-input multi-output (MIMO) channel, including a serial structure and a parallel structure. With singular value decomposition (SVD)-based precoding scheme, the MIMO channel ca...
A block fading model is considered for both the channel and the side information, whose states are assumed to be known only at the receiver. The optimality of separate source and channel coding in terms of average end-to-end distortion is shown when the channel is static, while the side ...
Three coding strategies are proposed where different LDPC source and channel coding setups are applied at the source node and the relay node. For each transmission strategy, we propose a graph mapping the whole network, over which iterative message-passing decoding is applied, and where the ...
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...
This paper proposes a novel digital deep joint source-channel coding (DeepJSCC) framework that achieves robust performance across diverse communication environments without requiring extensive retraining and prior knowledge of communication environments. Traditional digital DeepJSCC techniques often face ...
An SNR scalable video coder is used and unequal error protection (UEP) is allowed for each scalable layer. Our problem is to allocate the available bit rate across scalable layers and, within each layer, between source and channel coding, while minimizing the end-to-end distortion of the ...
