摘　　要：针对不同类型通信系统中对高性能帧同步码需求,给出了一种实用的帧同步码性能分析及高性能帧同步码搜寻的解决方案。结合目前广泛使用的LabVIEW软件,突破了软件自身数据类型的约束,提出了一种LabVIEW软件下任意长度码穷举算法,并以此算法为基础设计性能分析软件,从误同步概率和局部自相关函数2个角度对帧同步码的性能进行了分析。根据分析的结果,给出了2种性能评价准则下的帧同步码的选择方法,并给出了具体范例。A practical method of performance analysis and searching of high-performance synchronization codes is designed to meet different communication system demands.Based on the widely-used LabVIEW software and breaking through the restriction of its data type,an exhaustive algorithm of generating arbitrary-length codes using LabVIEW is proposed in this paper.Base on this,the software is designed and the performance analysis of frame synchronization codes is carried out from both aspects of false synchronization probability and local autocorrelation function.According to the result, some guides and examples are given in choosing synchronization codes by the two rules.
