In order to minimize mutual interference in radio communication, the radio station frequency assignment is studied. For the application of radio station networking, the reason why interference occurs in radio communication network is analyzed and a more realistic frequency assignment model based on multiple signal interference in radio communication network is designed. On this basis, a frequency assignment algorithm based on simulated annealing algorithm was designed by combining the genetic algorithm with simulated annealing algorithm. Then it was applid to an actual radio communication network. Simulation result shows that the algorithm performs better in global optimization and quick convergence.
