2 m -ary modulation creates m bit channels which are neither independent nor identical, and this causes problems when applying polar coding because polar codes are designed for independent identical channels. Different from the existing multi-level coding (MLC) and bit-interleaved coded modulation (BICM) schemes, this paper provides a convolutional polar coded modulation (CPCM) method that preserves the low-complexity nature of BICM while offering improved spectral efficiency. Numerical results are given to show the good performance of the proposed method.

卷积极性编码调制


2 m 元调制创建既不独立也不相同的m个比特信道，并且这在应用极性编码时会引起问题，因为极性代码是为独立的相同信道设计的。与现有的多级编码（MLC）和比特交织编码调制（BICM）方案不同，本文提供了一种卷积极性编码调制（CPCM）方法，该方法保留了BICM的低复杂性特性，同时提供了更高的频谱效率。数值结果表明了该方法的良好性能。
