摘要
结合理论与工程两个方面 ,在已有研究成果的基础上 ,提出了一种快速指数算法加非线性转移矩阵变换的跳频码序列产生方法 .其算法复杂度呈对数增长规律 ,具有快速运算的特点 .在转移矩阵取得最大秩时 ,生成的跳频码序列具有随机性和均匀性 .通过计算机仿真 ,对频率撞击特性进行了统计研究 。
Combining theory and a practical project, a generation of hopping patterns with fast exponent algorithm and non linear transferring matrix transformation is proposed on the basis of research achievements available. The complexity of this algorithm has an increasing pattern of logarithm, so it possesses the advantage of fast calculation. Moreover, the frequency hopping sequences generated are of randomness and regularity when the transferring matrix reaches its maximum rank. By computer simulation, a statistic study on the performance of frequencies collision is conducted for reference in theory or practical fields.
