Nonquasicatastrophic maximum transition run codes

Abstract

Nonquasicatastrophic maximum transition run (MTR) codes are introduced by defining a new t-constraint. Finite state transition diagrams (FSTD) exhaustively characterizing MTR (j,k,t) constraints for detector trellises that are unconstrained or incorporate the j-constraint are presented and their capacity is computed. It is shown that (G,I) constrained systems are a subclass of (j,k,t) MTR constrained systems.
