An Application in Frequency Assignment Based on Improved Discrete Harmony Search Algorithm

摘要：

In cellular mobile communication network, for using the limited available spectrum to meet the increasing demand of customer, it is important to scheme frequency source by applying some optimized algorithm.To the question, an improved discrete harmony algorithm is proposed, particle location update strategies of the particle swarm optimization algorithm is introduced, the probability of harmony memory size and the probability of pitch adjusting rate are adjusted dynamically, which improve the global optimization stability of the search results, enhance the universality and robustness of the algorithm, and improve the convergence rating and the convergence speed.Simulation results show that the improved algorithm applied to solve the problem of frequency assignment has achieved good results.
