| 摘 要： | 该文提出一种新的最佳相关信号,即伪随机屏蔽序列偶,研究了其变换性质和组合允许条件,运用这些性质和条件可以缩小伪随机屏蔽序列偶的搜索范围,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,搜索出若干长度的伪随机屏蔽序列偶.对伪随机屏蔽序列偶扩频通信系统的性能进行了仿真,仿真结果表明伪随机屏蔽序列偶作为扩频码的性能在一些场合要优于同长度的m序列.

| Abstract: | A new perfect correlation signal is proposed, which can be called as Pseudorandom Punctured Sequence Pairs (PPSP). The properties and combinatorial admissibility conditions of PPSP are studied. By making use of these properties and conditions, the efficiency of searching the PPSP can be improved significantly. As a computational illustration, a set of pseudorandom punctured sequence pairs are given. The performances of PPSP are analyzed and compared with m sequence in spread spectrum communication. The simulation results show that the performances of PPSP are better than m sequence in some conditions. |
