【Abstract】 Tiis paper deals with the design and realization of a simplified frequency hopping network of JITDS.Firstly,the construction of the frequency hopping sequences based on PN is introduced and some measures are employed to improve its performance of secrecy.Secondly,the necessity to determine there is a wide interval in the sequences by specific methods is ensured and then the network of frequency hopping is constructed.At last,the performance of the sequences is investigated according to a set of criteria by simulation.更多还原
