matlab语言添加噪声
- matlab语言添加噪声及相关程序， 在信号处理中经常需要把噪声叠加到信号上去，在叠加噪声时往往需要满足一定的信噪比，这样产生二个问题，其一噪声是否按指定的信噪比叠加，其二怎么样检验带噪信号中信噪比满足指定的信噪比。在MATLAB中可以用randn产生均值为0方差为1的正态分布白噪声，但在任意长度下x=randn(1,N)，x不一定是均值为0方差为1（有些小小的偏差），这样对后续的计算会产生影响。在这里提供3个函数用于按一定的信噪比把噪声叠加到信号上去，同时可检验带噪信号中信噪比。

- 为了提高四足机器人在复杂环境下的适应性,重点研究了采用飞行时间(TOF)原理相机的四足机器人环境感知策略并改进了地形识别及路径规划算法.首先采用高斯过程回归(GPR)模型对TOF相机的距离数据进行误差校正,解决了采用传统多项式或三角函数模型进行误差修正时模型阶次过高及函数组合复杂的问题.基于得到的环境深度信息,采用数字高程模型(DEM)进行地形描述,并通过计算各栅格的坡度、粗糙度、起伏度对地形进行识别.粗糙度由该栅格所处的坡度平面与其8邻域高程点的离散程度进行计算,避免了采用高程方差计算时对粗糙
