论文摘要
最近提出了通过极化调整后的卷积（PAC）代码，并引起了通道编码社区的兴趣，因为它们被证明可以针对（128,64）代码大小接近理论界限。在这封信中，我们提出了系统的PAC代码。多亏了系统的属性，观察到最高0.2 dB的比特率的提高，同时保留了帧率率性能。此外，提供了一种基于遗传叠加的构造方法，该方法是针对接近理论结合的。然后表明，使用提出的施工方法系统和非系统的PAC代码也可以接近理论界限，即使对于（256,128）等较高的代码尺寸也可以接近理论界限。
Polarization-adjusted convolutional (PAC) codes were recently proposed and arouse the interest of the channel coding community because they were shown to approach theoretical bounds for the (128,64) code size. In this letter, we propose systematic PAC codes. Thanks to the systematic property, improvement in the bit-error rate of up to 0.2 dB is observed, while preserving the frame-error rate performance. Moreover, a genetic-algorithm based construction method targeted to approach the theoretical bound is provided. It is then shown that using the proposed construction method systematic and non-systematic PAC codes can approach the theoretical bound even for higher code sizes such as (256,128).
