A Butterfly Structure for Rate 2/n Convolutional Codes
Summary :
In this letter, we propose a butterfly structure for rate 2/n convolutional codes to reduce the computational complexity of Viterbi decoders. By using the butterfly structure, the branch metric computation complexity of some best known codes can be reduced by a factor of 2 or 4.
