| Abstract: | The characteristics of finite input response sequences and the features of Hamming weights are investigated in convolutional codes. And an analytic solution for computing Hamming distances is proposed. The analytic method using these characteristics can take the place of computer simulation methods in searching good codes and computing Hamming weights. The proposed method can be used for interleavers design. |
