Several new complex equalizers applicable to QAM signals are presented. The equalizers, fully incorporating the obtained signal information and RBF's features, are constructed by radial basis function neural networks (RBFNs). The algorithms for them are also given. Theoretical analysis and experimental results show that the new algorithms have a better convergence property than those of the complex RBFNs based equalizers available.\;
