Abstract
A convolutional code having identical initial and final states is decoded by using the Viterbi algorithm to trace a path starting from a first state and ending at a second state. If necessary, the trace is repeated, starting from the second state, provided the second state is not the same as the first state. The output result is then obtained from the second trace.
