典型的多目标粒子群算法（CMOPSO)，附测试函数,注解详细，适合学习参考(A typical multi-objective particle swarm optimization (CMOPSO), attached to the test function, annotation detailed reference for learning)

This paper presents an algorithm for modulation recognition of received signals in the presence of additive white Gaussian noise (AWGN) with the use of the wavelet transform

本算法在训练步数、训练时间及其误差精度等方面都优于常规的模糊神经网络，其学习收敛速度快、误差曲线也更稳定。(the algorithm steps in training, training time and error accuracy is superior to the conventional fuzzy neural network, learning fast convergence, the error curve is more stable.)
