论文摘要
在本文中，我们首先提出了一种通用极性编码方案，用于具有非二元输入的平行高斯通道。假定编码器仅知道平行通道的总和容量，而不是任何单个通道的容量。通过将每个并行通道分解为t = [log2r]子通道，我们获得了MT二进制子通道。然后提出了在所有子通道中的超极地编码方案。当块长度足够大时，该方案可以实现总和容量。我们还讨论了对HARQ和MIMO系统的平行极性编码设计的应用。结果表明，对于块褪色通道，可以获得能力实现的HARQ方案，以及仅需要达到所有MIMO层的总和率的反馈的能力实现的MIMO设计。
In this paper, we first propose an universal polar coding scheme for parallel Gaussian channels with non-binary inputs. It is assumed that the encoder knows only the sum capacity of M parallel channels instead of the capacity of any single channel. By decomposing each parallel channel into T = [log2r] sub channels, we therefore obtain MT binary sub-channels. A super polar coding scheme that across all sub-channels is then proposed. This scheme can achieve the sum capacity when the block length is sufficiently large. We have also discussed the applications of parallel polar coding design for both the HARQ and MIMO systems. It is shown that a capacity-achieving HARQ scheme can be obtained for block fading channel and a capacity-achieving MIMO design that requires only the feedback of the sum rate of all MIMO layers can also be attained.
