摘要
介绍了一种以多层前向神经网络作为预滤波的自适应信号增强器,利用神经网络的高度非线性映射能力获得更好的参考信号,该滤波器对运动心电信号中的噪声去除取得了满意的效果。
In this pa pe r,a selfadaptive signal enhancer adopting multilayer feedforward network as pre filter is developed.Better reference signal can be obtained through neural netw ork's ability of high degree non-linear mapping.The filter can effectively re move the noise in exercise electrocardiogram signals.
