Zusammenfassung:In this paper, a new method for the decoding of DTMF signals is proposed. The approach, which applies the Arithmetic Fourier Transform, is more efficient, in terms of computational complexity, than existing techniques. Theoretical aspects and features that determine the accuracy and the complexity of the proposed method are discussed.
