中文摘要：
提出一种新的最佳相关信号，即几乎最佳屏蔽二进序列偶，研究了其变换性质和存在组合的允许条件．运用这些性质和条件可以缩小几乎最佳屏蔽二进序列偶的搜索范围，提高计算机搜索的效率．在此基础上编写了计算机搜索算法，搜索出若干长度的几乎最佳屏蔽二进序列偶．搜索结果表明，几乎最佳屏蔽二进序列偶具有较大的存在空间，可以应用到工程中．
英文摘要：
A new perfect correlation signal was proposed, which can be called as almost perfect punctured binary sequence pairs. Its properties and combinatorial admissibility conditions were studied. By making use of these properties and conditions, the searching efficiency for the almost perfect punctured binary sequence pairs can be improved significantly. A computational algorithm is compiled to find out a set of almost perfect punctured binary sequence pairs. The searching results show that the existent range of almost perfect punctured binary sequence pairs is so wide that they are suitable for engineering applications.
