Independent component analysis(ICA) and back propagation(BP) neural network are used for pattern recognition of Electronic-nose.Considered the cross sensitivity of gas sensor array for improving the identify ratio to electronic-nose.The by using a sensor array of four sensors is analyzed to measure data which is obtained mixture of CO

.The results showed that ICA can give a good classification for the gases data and eliminate the data correlation.The processing data is inputed to BP network
network structure is simplified
and the convergence speed of the BP network is enhanced greatly.Further the recognition ratio is improved highly with ICA and BP network to electronic-nose system.
