| Abstract: | The role of trellis termination in turbo codes is analyzed in point of the influence of trellis termination on the distance spectrum. The influence of trellis termination on the performance of turbo codes is studied by simulation. The simulation results show that turbo codes with trellis termination outperformed those without trellis termination. |
