  Abstract

The rate of the channel code can be controlled by various methods. Puncturing is one of the methods of increasing the code rate, and the original code before puncturing is called the mother code. Any (n, k) convolutional code is obtainable by puncturing some mother codes, and the process of finding the mother code is necessary for designing the optimum channel decoder. In this paper, we proved that any (n, n-1) convolutional code has (2, 1) mother codes regardless of the puncturing pattern and showed that they must be equivalent.
