| Abstract: | The effect of the self interleaving distance and correlative interleaving distance of the interleaver on the decoding performance was investigated. The functions of interleaving distance were put forward and a design rule of interleaver was presented. Based on the analysis, a new interleaver generated by using a linear recursion was proposed. Simulation results show that they exhibit good bit error performance. |

| Keywords: | Turbo codes self interleaving distance correlative interleaving distance linear iterative sequences |
