Simulation of Difference Frequency Hopping Source Based on Logistic Map

A simulation scheme of DFH Source based on Logistic Map is presented through the research of structure and characteristic of the DFH system . The modules of FH pattern, G function and signal waveform design are simulated and the performance of the FH sequences is checked. Finally simulation and performance analysis illustrate that the way can simulate the main character of typical DFH signal, and has better randomicity and uniformity. So it is an excellent alternative source for DFH communication research, and can act as a reference for actual design of DFH system.
