Abstract: Abstract As the efficient methods to determine the weight distribution of the convolutional code, there have been proposed the high‐speed algorithm based on the tree search on the trellis [1] and the variational method based on the variation of the weight of the code word [2]. This paper proposes a method to determine the weight distribution of the convolutional code with the coding ratio 1:2 where an algorithm (called modified variational method), which is efficient and can easily be realized on the computer…
