Abstract. In this paper an algorithm based on polyphase matrices for constructing a pair of orthogonal wavelet frames is suggested, and a general form for all orthogonal tight wavelet frames on local fields of positive characteristic is described. Moreover, an investigation regarding their properties by means of the Fourier transform is carried out.
