| 摘 要： | 介绍了一种在多址方式为TDMA的蜂窝制矿井数字移动通信系统中帧同步的实现，针对井下多径衰落大的特点，提出了一种新型的抗衰落帧同步保护方案。井将该方案与CCTTT推荐的帧同步保护方案进行比较，分别阐述两个方案的工作机制井分析它们的工作特点，理论分析和井下试验都表明CCTTT方案在多径衰落较严重的井下难以达到理想的通信效果。在误码率较高的井下环境，抗衰落保护方案的性能优于CCTTT方案，但抗衰落保护方案的实现对系统硬件要求很高。

| Abstract: | The approach of frame-sync protection for TDMA digital mobile cell communication system in the underground is presented. In view of the fact that effect of multi-path fading underground is serious, an new approach of frame-sync protection is put forward accordingly. By comparison of this new approach of frame-sync protection with the one CCITT recommended, work mechanism and character of both frame-sync protection measures are analyzed respectively. Both underground experiment and theoretic analysis reveal that using CCITT approach is difficult to achieve satisfactory result in underground environment due to deep multi-path fading. The paper concludes that the performance of this new approach is better underground where error rate is higher due to the heaviness of multi-path fading, but the CCITT is easy to accomplish |
