Center node: "channel coding at low capacity"
  Abstract: Low-capacity scenarios have become increasingly important in the technology of Internet of Things (IoT) and next generation of mobile networks. Such scenarios require efficient, reliable transmission of information over channels with extremely small capacity. Within these constraints, the performance of state-of-the-art coding techniques is far from optimal in terms of either rate or complexity. Moreover, the current non-asymptotic laws of optimal channel coding provide inaccurate predictions for coding in the low-capacity regime. In this paper, we provide the first comprehensive study of channel coding in the low-capacity regime. We will investigate the fundamental non-asymptotic limits for channel coding as well as challenges that must be overcome for efficient code design in low-capacity scenarios.
