| Abstract: | The hierarchy genetic algorithm was used to determine the RBF neural network structure in the modulation identification of communication signals.A new fitness function was given,which is simple and contains less undetermined parameters.Also,the correlation tournament selection method was used to improve the selection operator,which increases the diversity of population evolution and avoid the premature convergence.Simulation results show that the new algorithm can better determine the classifier structure a... |
