An Interference-Free Frequency Assignment Method Based on Hybrid Pattern
Keywords:
Electromagnetic spectrum management, frequency assignment, genetic and simulated annealing algorithm, sequential graph coloringalgorithmAbstract
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.
