Abstract In the applications of wavelet, it is the most difficult and cumbrous to select the suitable wavelet bases. In this paper, a general construction method of biorthogonal bases of perfect reconstruction wavelet is proposed by using the transmission functions or filters. According to the conclusion, something only to do is to choice the suitable coefficients a,y(co) for constructing the wavelet bases of perfect reconstruction which has special properties. So, this conclusion is important to the applications of wavelet.
