— Interference-free frequency assignment for wireless electronic equipment on the same spot is a key technology for electromagnetic spectrum management and utilization. In this article firstly study the restrictive conditions for same frequency, adjacent frequency, intermodulation and harmonic interference. And then acquire the relations between distance of stations on the same spot and interference-free frequency interval by experiments. Finally put the experiment result and the priority limit conditions into the improved frequency assignment algorithm based on hybrid pattern with sequential graph coloring algorithm and genetic and simulated annealing algorithm, and accomplish the interference-free frequency assignment on the same spot.
