A general method of coding over expansion is proposed,which allows one to reduce the highly non-trivial problems of coding over analog channels and compressing analog sources to a set of much simpler subproblems, coding over discrete channels and compressing discrete sources. More specifically, the ...
摘要: This paper investigates the tradeoffs of source coding, channel coding and spreading in CDMA systems. We consider a system consisting of an image source coder, a convolutional channel coder, an int...关键词: bandwidth allocation channel estimation direct-sequence CDMA frequency selective ...
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 ...
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...

As mentioned in Chapter 2, lossy compression is generally required for video transmission applications. It is well known that the theoretical bounds for lossless compression are the entropy of the source. In the same way entropy determines the lowest pos

In the first SCC Strategy 1, we distributed the source and the channel coding operations between the source and the relay nodes, respectively. On the opposite, in the second SCC Strategy 2, we proposed an LDPC channel coding at the source node and an LDPC source coding at the relay node....

Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost tradeoff over additive white Gaussian noise cha
