Threshold decoding selected rate one-half and one-third convolutional codes (Corresp.)

The results of a search for threshold decoding equations are presented for a selection of different length, rate
\frac{1}{2}
and
\frac{1}{3}
convolutional codes. The decoders corresponding to these equations are simulated on a computer in order to perform an error analysis. Error analysis for seven rate
\frac{1}{2}
codes (lengths span the range from
n = 4
to
22
) and five rate
\frac{1}{3}
codes (lengths span the range from
n = 6
to
21
) are presented.
