子波变换现已成为一种重要的信号处理方法.本文提出一种以TI公司DSP(TMS320C30)为基础的一维正交离散子波变换系统的实现方法,用该系统实现 Mallat 正交子波快速分解与重构算法,并详细介绍了该系统的电路设计原理和相应的软件流程.测试结果表明该系统重构信号的绝对误差小于10~( -3)。
Wavelet transform has now become an important signal processing method. This paper presents a TI DSP (TMS320C30) -based one-dimensional orthogonal discrete wavelet transform system implementation, the system Mallat orthogonal wavelet fast decomposition and reconstruction algorithm, and details of the system Circuit design principles and the corresponding software process. The test results show that the absolute error of the reconstructed signal is less than 10 ~ (-3).
