| Abstract: |
| This paper researches on the optimizing hardware realization of Turbo codes according to the contradiction between hardware cost and decoding performance. A high efficient method for implementation of Turbo codes based on Max - Log - Map algorithm is proposed. It turns out to be a good tradeoff between the performance and the hardware cost. |
