摘　　要：提出了一种具有良好周期相关特性的新型离散信号,即广义伪随机屏蔽二进序列偶,给出了其变换性质和组合允许条件.在这些性质的基础上利用计算机搜索出若干小体积的广义伪随机屏蔽二进序列偶,并与伪随机二进序列偶进行了比较,结果表明广义伪随机屏蔽二进序列偶具有很高的能量效率和较大的存在空间,可以作为同步码或多用户码应用于实际工程当中.A new periodic correlation discrete signal is present, which is generalized pseudorandom punctured binary sequencepairs. The transformation properties and combinatorial limited conditions ofit were given out. Based on these properties many generalized pseudorandom punctured binary sequence pairs with small volume were search out, and compared to pseudorandom binary sequence pairs. The searched results show that it have such high energy efficiency and exist in large space, and feasible for engineering applications as synchronization codes and multi-user codes.
