%X A new threshold function based on the wavelet threshold de-nosing was presented.It overcame the shortcoming of the hard threshold with discontinuous function and solved the problem of the permanent bias in soft threshold function.At the same time,the new function didn't need to choose parameters.Simulation result indicates that the new threshold function is effective and predominant than other threshold functions.
