摘要：

It is known that an (n, n - 1) non catastrophic antipodal punctured convolutional encoder of memory.. is minimal. That is, the corresponding code cannot be produced by an encoder of smaller memory size. In this letter it is shown that the trellis module of a code produced by an (n, n - 1) non catastrophic punctured convolutional encoder is optimum, if and only if the encoder is antipodal.
