论文摘要
与刻度间隔的编码调制相比，多级编码通常假定的缺点是其高潜伏期：实际上，必须顺序解码级别。在本文中，我们将极地代码考虑对每个级别进行编码。我们表明，使用每个极性代码的连续策略列表解码的多级方案的解码时间复杂性仅是单个极性代码之一，而不论信号噪声比率和级别的数量如何。
A commonly assumed drawback of multi-level coding, compared to a bit-interleaved coded modulation, is its high latency: Indeed, the levels must be decoded sequentially. In this paper, we consider polar codes to code each level. We show that the decoding time complexity of the multi-level scheme, using successive-cancellation list decoding for each polar code, is only 1.5 times the one of a single polar code, regardless of the signal-to-noise ratio and the number of levels.
