摘要
基于完全非线性函数,构造了一类新的跳频序列族。根据完全非线性函数的性质,证明了这些跳频序列具有良好的汉明自相关和汉明互相关特性。利用不同的完全非线性函数,可以得到不同的并且具有最优汉明相关性能的跳频序列族。
A new family of frequency-hopping sequences was constructed based on perfect nonlinear function. It was proved that these sequences had good Hamming auto-correlation and cross-correlation properties according to the properties of perfect nonlinear function. Based upon different perfect nonlinear functions, different frequency-hopping sequence families with optimal Hamming correlation property could be obtained.
