摘要
基于二维周期互补阵列偶集,通过设计一种新型的移位序列,利用交织方法构造二维二元零相关区周期互补阵列偶集,进而利用一种新的逆Gray映射,生成二维四元零相关区周期互补阵列偶集.结果表明,阵列偶集中各个子集之间具有良好的相关特性.该方法将周期互补序列偶的思想应用到阵列集的构造中,给出了一种二维四元零相关区周期互补阵列偶集的构造方法.该构造方法根据零相关区长度的取值不同,能够获得大量新的构造结果,从而为实际工程提供更多的信号选择.
Based on two-dimensional binary periodic complementary sequence pairs sets, the two-dimensional binary periodic complementary array pairs sets with zero correlation zone is constructed by the new interleaving technique and shift sequence, then use the new inverse Gray mapping to construct the two-dimensional quaternary periodic complementary array pairs sets with zero correlation zone. The resutts show that there are good correlation properties between the subsets of array paivs sets. In this method, the concept of periodic complementary sequence pairs is introduced into the array structure and a method is used to construct, the two-dimensional quaternary periodic complementary array pairs sets with zero correlation zone. According to the different values of zero correlation zone length, a large number of new structural results can be obtained, which can provide more signal selection for practical engineering.
