There exists an identical high rate ordinary convolutional code with a punctured convolutional code. We show a method for obtaining good rate R = (n − 1)/n punctured convolutional codes through the identical codes with the best punctured convolutional codes of rate (n − 1)/n obtained by exhaustive searches for rate 1/2 original codes and puncturing matrices, and the method can find out punctured convolutional...
Punctured convolutional codes are error-correcting codes that can be used to achieve reliable data transfer in digital communication systems. This paper considers a method to search good high-rate punctured convolutional code encoders using dual codes, which are often utilized to evaluate block codes. A low-rate R = 1=n convolutional code has a dual code identical to a punctured convolutional code...
