The acoustic recognition technology in wireless sensor surveillance network in wild environment is facing the challenge of the complicated and strong acoustic noise
especially the effect of the wind noise.Independent component analysis(ICA)method has a good performance in denoising in complicated environment.On the basis of kernel independent component analysis(KICA)
a denoising scheme for single acoustic sensor is designed.It is a typical nonlinear independent component analysis method.Through denoising simulation experiment
the KICA algorithm is compared with the typical algorithm of ICA method
fast ICA algorithm.Results show that in a denoising application aimed at the strong wind noise in wild environment
with the mean square error criterion and the correct classification ratio criterion
KICA algorithm is superior to the fast ICA algorithm.
