【摘 要】

：

针对从含噪原始信号中提取位置以及速度信息,经典跟踪微分器存在不能很好兼顾相位滞后和噪声放大问题、参数多,调试复杂等不足.在跟踪微分器等效线性分析基础上,提出复合形式跟踪微分器,用于电容式位移传感器位置信号跟踪以及速度信号估计,通过MATLAB\\SIMULINK仿真以及实验平台测试,结果表明:在跟踪频率1 Hz、幅值1含噪声正弦信号中,复合跟踪微分器能光滑逼近原始位置信号,且能有效进行速度估计,相较于经典跟踪微分器,复合跟踪微分器跟踪相位滞后小0.03 rad,能更好兼顾跟踪信号相位滞后及速度信号噪声

基于基频的梅尔倒谱系数在车辆识别中的应用

用传统的梅尔倒谱系数作为特征进行车辆识别时,识别效果易受噪声干扰.为增强特征鲁棒性,提出一种加权的基频自适应梅尔倒谱系数特征提取算法.首先用能熵比法对车辆声音信号进行端点检测;然后提取车辆信号的基频,自适应构建三角滤波器组,提高滤波器对基频的感知敏感度;最后对基频自适应梅尔倒谱系数进行F比加权.实验结果表明,与传统梅尔倒谱系数相比,在识别车辆时,加权的基频自适应梅尔倒谱系数识别准确率提高7.10％,虚警率降低3.93％,漏警率降低7.10％.
