Abstract :
The results of an extensive search for short and moderate length polynomial convolutional encoders for time-invariant tail-biting representations of block codes at rates R=1/4, 1/3, 1/2, and 2/3 are reported. The tail-biting representations found are typically as good as the best known block codes
