| Abstract: | The wavelet transform, as an important method has a good property in local time - frequency space. The fixed - point DSPs are applied-widely in engineering applications since its less costs and higher performance. In this article, the wavelet theory and algorithm are described. And the implementation of the algorithm is given corresponding to 16 - bit fixed - point DSPs from Texas Instruments. |
