Orthogonal Multicarrier Division Duplexing for Point-to-Point Communications
Traditional communication systems adopt either Time Division Duplexing (TDD) or Frequency Division Duplexing (FDD). TDD requires guard interval and FDD needs guard band. Orthogonal Multicarrier Division Duplexing (MDD) is a new duplexing scheme, which can avoid both guard interval and guard band. In this paper, the authors propose a new MDD scheme with a group-wise subcarrier partition, which is more robust to the Inter-Carrier Interference (ICI) than the subcarrier-wise scheme, while keeping the same or better outage performance. They introduce somewhat modified block outage probability and block outage capacity metrics which are defined in such a way to facilitate the analysis and design of duplexing schemes in Point-To-Point (P2P) system.
