摘要
小波变换具有良好的时——频局部性,是分析奇异信号的重要方法。定点DSP在工程中的应用十分普遍,具有低成本,高性能的特点。利用DSP实现小波变换可以满足工程是实时性的要求。文中简要介绍了小波变换理论及算法,并结合TI公司的16位定点DSP说明算法的实现。
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.
