基于小波变换的脉搏波信号去噪
Pulse Wave Signal Denoising Based on the Wavelet Transform
【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.
【Abstract】 Mallat algorithm for completing the multi-resolution analysis and denoising of the pulse wave is used, and themethod has many advantages, including a constant quality factor, a small amount of the computation and a flexible de-composing scale. The whole system based on MSP430 chip realize the function of signal detection preferably, and it isalso proved to be valuable in practice.
