Vehicle audio signal estimation of AR model and power spectrum estimation based on artificial neural network

A method for estimating AR model parameters and power spectrum of vehicle audio signals was introduced. Three layer with recessive neuron as linear transfer function in artificial neural network was used in the paper. Experiment proved that the AR model parameters and power spectrum of vehicle audio signals estimated by the method of artificial neural networks can get the same result as Burg algorithm. This result showed that the method of artificial neural networks was effective.
