Channel Coding Techniques for Ultra-Reliable and Low-Latency Communication
摘要
Abstract
One of the hottest topics in the field of wireless communication is ultra-reliable and low-latency communi-cation(URLLC),where channel coding with short-and-medium length plays a critical role.Unlike the case for long codes,in the finite code length regime,the coding rate is constrained by the error performance,thus tailored coding construction,decoding algorithm design,and performance analysis and optimization are required.At present,there are studies on coding technologies such as polar codes and tail-biting convolutional codes for short-and-medium length codes,but they are mainly optimized designs for specific code lengths and rates,which are difficult to meet the requirements of flexible coding for practical applications.Based on this,this paper summarizes and discusses the state-of-the-art coding technology for short-and-medium length.Firstly,we review the theoretical bounds for the performance of finite-length codes.Then,we analyze the coding technologies proposed in recent years,and compare their advantages and disadvantages.Finally,we discuss in detail new coding technologies for URLLC,and we prospectively explore the future research directions and development trends of channel coding techniques for ultra-reliable and low-latency communication.关键词
