摘　　要：利用Mallat算法对脉搏波信号进行多分辩分析和去噪,具有品质因数恒定、运算量小、分解尺度可调的优点,且去噪效果好.整个系统基于MSP430单片机实现,完成了对脉搏波检测的功能,效果较好,有一定的实际应用价值.Mallat algorithm for completing the multi-resolution analysis and denoising of the pulse wave is used, and the method has many advantages, including a constant quality factor, a small amount of the computation and a flexible decomposing scale. The whole system based on MSP430 chip realize the function of signal detection preferably, and it is also proved to be valuable in practice.

关 键 词：脉搏波 小波变换 MALLAT算法 信号去噪
