【摘要】 该文在现有研究结果的基础上,针对CHESS系统提出了一种新的G函数算法,该算法将总频率集中的频点随机分为m=2BPH个子频率集,根据待发送的信息以及信息码与子频率集的对应关系得出下一跳的频点,由检验结果看出该方法在以往的基础上提高了系统的一维均匀性、二维连续性及随机性,取得了较好的效果。更多还原

【Abstract】 On the basis of existing references, this paper proposes a new G function algorithm for the HF high speed FH CHESS radio system. In the algorithm, the frequencies are grouped into m = 2BPH subsets. The next hopping frequency is chosen according to the coding series and the corresponding relationship between the codes and the frequency subsets. The performance test results show that the algorithm has more superiority in 1-dimensional uniformity, 2-dimensional continuity and randomness of the hopping series compared with previous G function algorithm.更多还原
