跳频系统中基于非重复序列的同步频率设计

Design of Synchronization-Frequency Based on Nonrepeating Sequence in FH Systems

将由M序列构造的非重复序列与另一不具有非重复性的序列并联得到一组同步频率。该同步频率在非重复序列的周期内也具有非重复性,无需进行检测和置换即可用于跳频同步。进一步改进算法后,在DSP上实现了该算法。计算机测试表明,该算法设计的同步频率能较好地满足跳频系统对同步频率的要求。

A group of synchronization-frequency(SF) is obtained by combining a nonrepeating sequence formed by M sequence with another sequence without nonrepeating performance.This kind of SF is of nonrepeating performance within the period of its nonrepeating sequence,and it can be applied to the synchronization of FH systems without any detection or replacement.With some improvement,the arithmetic is realized in DSP.Computer testing result show that the SF designed by the arithmetic can satisfy the demand of FH systems.
