| 摘要: |
| 针对NDA-FF（Non-data-aided Feedforward）载波相位同步估值展开（Unwrapping）中的拖延现象（Hang-up）进行了研究，将对相角的处理改为对复相位的处理，提出了一种展开环路的无拖延改进方案，并利用计算机仿真对该方案进行了性能分析。仿真结果显示该方案解决了原有的拖延问题。 |

| () |
| Abstract: |
| Hang-up in estimating unwrapping of NDAFF(Non-datn-aided Feedforward) carrier phase synchronization is researched.An improved method about unwrapping is put forward based on the processing of the complex phase instead of the phase.Its performance is analyzed by computer simulation.The result shows the hang-up problem is resolved by the new method. |
| Key words: phase synchronization hang - up unwrapping NDA - FF post - processing |
