Polar codes have attracted the attention of academia and industry alike in the past decade, such that the 5th generation wireless systems (5G) standardization process of the 3rd generation partnership project (3GPP) chose polar codes as a channel coding scheme. In this tutorial, we provide a description of the encoding process of polar codes adopted by the 5G standard. We illustrate the struggles of designing a family of polar codes able to satisfy the demands of 5G systems, with particular attention to rate flexibility and low decoding latency. The result of these efforts is an elaborate framework that applies novel coding techniques to provide a solid channel code for NR requirements.

5G新无线电中Polar码的设计


Polar码在过去十年中引起了学术界和工业界的广泛关注，以至于第三代合作伙伴计划（3GPP）的第五代无线系统（5G）标准化进程选择了Polar码作为信道编码方案。在本教程中，我们描述了5G标准采用的Polar码的编码过程。我们阐述了设计一系列能够满足 5G 系统需求的 Polar 码的困难，特别关注速率灵活性和低解码延迟。这些努力的结果是一个精心设计的框架，该框架应用新颖的编码技术来为 NR 要求提供可靠的信道代码。
