Multipled Block Codes, Hunting-Free Reframing, Header type frame, Coding efficiency, violation compensation
Application of multipled block codes (MBCs) for realizing new flexible and efficient transmission systems that feature in hunting-free reframing and asynchronous multiplexing is investigated. First, the principles of MBC are overviewed to show the capacities of filterless clock recovery. Next, it is shown how MBC line code can attain hunting-free reframing by the use of coding rule violation with violation compensation. Then frame design without the use of violation compensation is discussed. Finally, the feasibility of hunting-free reframing without violation compensation is tested in an experimental system.
