摘要
基于辛普森云模型,提出一种新的短波差分跳频(DFH)频率转移函数(G函数)算法,并对该G函数产生的跳频图案进行了数值仿真和分析。仿真结果表明:利用该G函数产生的跳频图案具有很好的汉明相关性、均匀性和连续性,并具有较好的宽间隔特性,且由于采用扩展形式的G函数,函数的复杂度大大提高,具有较强的抗破译性。
A novel frequency transition function (G-function) of shortwave DFH (differential frequency hopping) based on Xinpson cloud model is proposed. The FH pattern generated by the proposed G-function is simulated and analyzed. Numerical simulation results show that the FH pattern provides good Hamming correlation property, uniformity, continuity, and a preferable frequency spacing characteristic, furthermore, it also provides high complexity and privacy due to the application of the extended G-function.
