桥函数及广义桥函数的研究进展

Research Advance on Bridge Function and Generalized Bridge Function

桥函数和广义桥函数均为三值函数系 ,都是将初始序列经复制方式和移位方式变换后而形成的 .它们包括了一些常见的非正弦正交函数 ,如沃尔什函数和方波函数等 .简要介绍了近 1 0年来北京航空航天大学通信与电子系统博士点在非正弦正交函数方面研究的一些新进展 ,重点介绍了复制理论和广义复制方法 ,桥函数、广义桥函数的复制生成方法。

Bridge Function and Generalized Bridge Function are all three-valued function, and are made by initial sequence according to copied or shifted ways. They include some familiar orthogonal function of non-sine, such as Walsh Function. This paper briefly introduced some research advance on this subject, emphasized to introduce the copy theory and generalized copy method. The process of making (Generalized) Bridge Function, its property and application, was introduced briefly.
