Abstract

The rapid revolution of mobile communication technology provides a great avenue for efficient information transmission to facilitate digital multimedia services. In current 5G systems, broadcasting technology is used to improve the efficiency of information transmission, and polar codes are adopted to improve data transmission reliability. Reducing the decoding latency of polar codes is of great importance for ultra-low-latency and reliable data transmission for 5G broadcasting, which still remains a challenge in digital broadcasting services. In this paper, we propose an aggregation method to construct constituent codes for reducing the decoding latency of polar codes. The aggregation method jointly exploits the structure and reliability of constituent codes to increase the lengths of constituent codes that can be decoded in parallel, thus significantly reducing the decoding latency. Furthermore, an efficient parallel decoding algorithm is integrated with the proposed aggregation method to efficiently decode the reliable constituent codes without sacrificing error-correction performance. Simulation results show that the proposed method significantly reduces the decoding latency as compared to the existing state-of-the-art schemes.

为 5G 数字广播服务快速解码极性编码

移动通信技术的迅猛发展为高效信息传输提供了广阔的空间，从而促进了数字多媒体服务的发展。在当前的 5G 系统中，广播技术被用来提高信息传输的效率，极地编码被用来提高数据传输的可靠性。降低极性码的解码延迟对 5G 广播的超低延迟和可靠数据传输具有重要意义，而这在数字广播服务中仍是一项挑战。本文提出了一种聚合方法来构建极性码的组成码，以降低极性码的解码延迟。该聚合方法共同利用了组成码的结构和可靠性，增加了可并行解码的组成码长度，从而显著降低了解码延迟。此外，一种高效的并行解码算法与所提出的聚合方法相结合，可在不牺牲纠错性能的情况下高效解码可靠的组成码。仿真结果表明，与现有的先进方案相比，所提出的方法大大减少了解码延迟。

期刊介绍： The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
