基于BSC的非均匀输入信道多级编码及无速率传输
Multilevel Coding for Channels with Non-uniform Inputs and Rateless Transmission over the BSC
摘要:
我们考虑编码方案的渠道与非均匀输入(NUI),标准的线性分组码不能直接应用。我们表明,多级编码(MLC)与一组线性码和一个确定性映射器可以实现的信息速率的信道与NUI。然而,映射器不必是一对一的。作为所提出的MLC方案的应用,我们提出了一个无速率传输方案在二进制对称信道(BSC)。
英文摘要:
We consider coding schemes for channels with non-uniform inputs (NUI), where standard linear block codes can not be applied directly. We show that multilevel coding (MLC) with a set of linear codes and a deterministic mapper can achieve the information rate of the channel with NUI. The mapper, however, does not have to be one-to-one. As an application of the proposed MLC scheme, we present a rateless transmission scheme over the binary symmetric channel (BSC).
