Abstract: In this paper, a mathematical framework for APP decoding of binary
linear block codes on the Gilbert-Elliott channel (GEC) is
developed. For this purpose, the theory of group representations
and finite state machines are combined for deriving a `dual APP'
algorithm for the GEC. The presented approach belongs to the class
of single-sweep algorithms. As such, complexity benefits of the
dual approaches are preserved while additional storage savings are
obtained over other single-sweep algorithms. The presented APP
decoding technique also takes account of the increasing demand for
efficient utilization of bandwidth making higher rate codes more
desirable.
