Frequency transition function of DFH system based on cloud model
Zhu Yi-chao · Chinese Journal of Radio Science · 2006
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.
