摘要

观察到函数与迹函数组成的非零Hadamard谱的预像集与函数无关的现象，给出了用不同的弯曲函数构造多个弯曲函数信号集的方法。讨论了它们的相关性和高阶移差性。作为一个副产品，多个弯曲函数信号集的并集产生了一个低相关带的信号集，并且比其他已知结构的信号集大得多。

Correlation of Multiple Bent Function Signal Sets

Observing a phenomenon that the pre-image set of nonzero Hadamard spectra of the composition of a function and a trace function is independent of the function, a construction of multiple bent function signal sets using different bent functions is given. Their correlation and high-order shift-distinct property are discussed. As a by-product, the union of the multiple bent function signal sets produces a signal set with low correlation zone and much larger size of the other known constructions.
