为了解决传统固定系数滤波器不能处理无法预知信号和噪声特性，提出一种基于System Generator 的音 频数字滤波器的设计方案。介绍了自适应滤波器基本原理及算法，采用LMS 算法并利用System Generator 构建了滤 波器仿真模型。仿真结果证明：经过自适应滤波器的处理后，可较好地滤除信号中的噪声；该方法设计的滤波器有 效地实现了对音频信号的自适应滤波，滤波效果良好。
基于Kalman滤波农用车辆导航定位方法（Positions Research of Vehicle Navigation System Based on Kalman Filter）
车辆导航 定位 Kalman滤波
2009/11/3
因RTD-GPS定位精度不能满足农田导航作业的需要，研究了一种提高农用车辆自动导航定位精度的方法。建立天线补偿模型，对GPS天线晃动引起的误差进行了补偿；建立基于Kalman滤波模型，融合多传感器信息；使用自主开发的基于VRS的GPS接收机，作为RTD-GPS。将RTD-GPS、电子罗盘以及速度传感器获得信息进行Kalman滤波，其结果和高精度GPS数据进行了比较。实验证明，直线跟踪中，平均偏差由...
