基于小波神经网络的调制信号识别方法
A recognition method on modulation signal based on wavelet network
摘要
Abstract
In order to overcome single neural network some weakness that it is difficult to expand, modify and maintain the neural network with large categories, a recognition method based on wavelet and RBF network array is used to divide wireless communication modulation signals. The feature extractions of three kinds of analog signals and six digital signals are picked up by a wavelet decomposition method and then feature extractions are classified by RBF neural network array. The simulation results show that the design combined with the wavelet analysis and neural network array makes the modulation category detection system of the wireless communication signal to achieve a-bout 90% performance when SNR is ?0 dB, and the detection rate in the multiple categories is improved.关键词
