Seeking the optimum frame synchronization performance is critical to improve the efficiency of data receiving. According to the frame synchronization strategy in national lunar mission, frame synchronization simu- lation software was completed and verified. This software simulation platform was used to find optimal parameter set- ting method for frame synchronization strategy in the case of high error bits rate. Simulation method was discussed to explore optimal parameters setting for frame synchronization by use of the software simulation platform. Some stan- dards were established to measure the frame synchronization performance, and according to the results of frame syn- chronization simulation, evaluate the frame synchronization performance in conditions of different parameters setting. In the end, the article summed up a set of methods for seeking optimum frame synchronization parameter setting by use of this software, and by this way the frame synchronization simulation test data was generated. The report of optimum frame synchronization was completed on how to set the frame synchronization parameters after completely data analy- sis. The software's correctness was tested by equipment in national lunar exploration mission, and the optimum frame synchronization report can be consulted in data receiving system of deep space mission in future.
