摘　　要：在杂交桥函数研究的基础上,用重组杂交的方法,得到一种新型三值函数,并命名为重组杂交桥函数,其函数对应矩阵的列向量即为重组杂交桥函数的函数序列。该函数序列具有分组正交性和良好的自相关特性,并且序列中零的个数可调,可以得到更多具有零相关窗或低相关窗的序列族,这不仅丰富了函数序列的生成方法,而且进一步完善了杂交桥函数理论体系。Based on the study of Hybrid Bridge function,a new three-valued function,which is named Restructured Hybrid Bridge Function,is created with the generation method of Restructured-Hybrid.The column vector of the function matrix is the Restructured Hybrid Bridge Function sequence.The number of zeros in the sequence is adjustable,and the characteristics of group orthogonality and better autocorrelation are proved by strict mathematical processes.More sequence sets with zero correlation zones or low correlation zones can be obtained by this specific sequence construction method,which not only enriches the generation methods of spreading sequences,but also further improves the theoretical system of the Hybrid Bridge function.
