Tailbiting codes encoded by feedback convolutional encoders are studied. A condition for when tailbiting will work is given and it Is described how the encoder starting state can be obtained for feedback encoders in both controller and observer canonical forms. Finally, results from a search for systematic feedback encoders that encode tailbiting codes with good decoding bit error probabilities are presented.
