| 摘 要： | Turbo码的提出使系统的性能对同步参数变得极为敏感。文章利用Turbo同步的方法来对Turbo系统进行迭代参数估计,并用插值的方法来减少译码复杂度,最后针对MSK信号给出同步算法。仿真结果表明,在少量增加译码复杂度的情况下,Turbo同步能够使系统获得与严格同步近似的性能。

| Abstract: | As Turbo codes were proposed,the performance of system was sensitive to synchronization parameters. Turbo synchronization was utilized to iteratively estimate parameter for Turbo system,and interpolation was used to reduce decoding complexity. The synchronization arithmetic was provided for MSK signal in the sequel. The simulation results showed that the Turbo synchronization,with a little addition of complexity,could achieve approximate perfor-mance comparable with the severe synchronization. |
