On Optimal Two-Priority-Level Codes in Mmwave Networks

This paper proposes a novel coding scheme to ensure resilience in millimeter-wave networks, where links are highly sensitive to blockages. The proposed scheme deploys multilevel codes to control the received information and provide different reliability guarantees for different information streams based on their priority. Unlike traditional multilevel coding designs, the proposed scheme maintains low design and operational complexity as the number of paths in the network increases. The achievable rate region of the proposed scheme is characterized and shown to be information-theoretical optimal for the case of two priority levels.
