Recent Advances in Spatially Coupled Codes: Overview and Outlook
For coding theorists and communication engineers, this paper provides a structured overview of spatially coupled codes, but it is a survey without new results.
This survey reviews recent advances in spatially coupled codes, highlighting their excellent waterfall and error floor performance, and discusses their design and future research directions.
The concept of spatial coupling is among the most significant breakthroughs in coding theory over the past decade. The excellent waterfall and error floor performance of spatially coupled codes has positioned them as promising coding candidates for future communication and data storage systems. This article presents an overview of recent advances in spatially coupled codes. In particular, we first review several representative examples of recently proposed spatially coupled codes and highlight their unique features that make them appealing for different applications. Next, we discuss the useful properties of spatially coupled codes and how to design good spatially coupled codes. The article concludes with some future research directions and open problems.
