Advanced coding techniques for 5G communications systems and beyond

未来的无线系统将构建一个包含约7万亿无线连接的超连接社会。这需要设计一种新的空中接口，在不同频段和发射功率限制下工作的异构设备将共存。作为这一目标的一部分，移动产业生态系统和学术研究人员正在几个技术前沿合作，以开发和标准化所需的空中接口（例如第五代无线系统：5G）。任何现代通信系统的一个重要组成部分是信道编码，它保护数据免受不必要的周围噪声/干扰。考虑到未来无线系统的严格性能指标（极高的数据速率，非常高的能效和低延迟），世界各地的研究实验室和电信公司都专注于设计实用高效的信道编码解决方案。特别是，极码和低密度奇偶校验（LDPC）码是关注的中心。事实上，在最近的3GPP会议（2016年11月）上，已经决定在5G中同时使用极性码和LDPC码。该小组还鼓励研究人员解决现有问题并优化这些代码。本文的目标是在实际假设下开发低复杂度的容量逼近极码和LDPC码。我们将重点关注极地和LDPC码在5G网络和其他新兴技术（如物联网）中的应用。这项工作将与我们的行业合作伙伴TELUS公司（一家拥有1250万客户连接和近125亿美元年收入的电信公司）一起完成。加拿大一直是ICT世界的主要国际贡献者。加拿大信息通信技术行业由大约36,000家公司组成，直接创造了约5%的国民生产总值。该项目产生的任何新技术都将使加拿大信息和通信技术公司受益，从而加强它们的全球竞争力。

Future wireless systems will build a hyper-connected society that encompasses around 7 trillion wireless connections. This requires devising a new air interface where heterogeneous devices working under different frequency bands and transmit power limits will coexist. As a part of this goal, the mobile industry ecosystem and academic researchers are working together on several technical fronts to develop and standardize the needed air interfaces (for example the fifth generation wireless systems: 5G). A vital component of any modern communication system is channel coding which protects data against the unwanted surrounding noise/interference. Considering the stringent performance measures of future wireless systems (extreme data rates, very high energy efficiency and low latency), research labs and telecommunication companies around the world are focused on devising practical and efficient channel coding solutions. In particular, polar codes and low-density parity check (LDPC) codes are at the centre of attention. In fact, in the latest 3GPP meeting (November 2016), it was decided that both polar codes and LDPC codes will be used in 5G. The panel also encouraged researchers to work around existing problems and optimization of these codes.This proposal, aims at developing low-complexity capacity-approaching polar and LDPC codes under practical assumptions. Our focus will be on the applications of polar and LDPC codes in the 5G networks and other emerging technologies (e.g., Internet of Things). This work will be done together with our industry partner, TELUS Corporation (a telecommunication company with 12.5 million customer connections and close to $12.5 billion annual revenue)Canada has been a major international contributor in the world of ICT. The Canadian ICT sector consists of about 36,000 companies that directly generate about 5% of the national GDP. Any new technology generated in this project would benefit the Canadian ICT companies, reinforcing their global competitiveness.
