What for Linear regression is used? We can predict one variable from another Y = a+ bX b = slope a = intercept (constant ) Correlation Coefficient (r) : A measure of association between two variables. -What for Linear regression is used

运用相关矩阵法，通过计算2 根天线之间的相关系数、多输入多输出(MIMO)的相关矩阵，得到MIMO 信道系数矩阵，在其中加 入智能天线(SA)的导向向量和赋形向量，得到MIMO/SA 矩阵，由此实现对MIMO/SA 多天线空时信道的建模。-Use of the correlation matrix method, the multi-input multi-output (MIMO), correlation matrix, obtained by calculating the corre

首先将非平稳的故障振动信号进行双树复小波包分解，得 到不同频带的分量；然后对每个分量求其峭度值和相关系数并进行比较；最后选取峭度值和相关系数较大的分量 进行软阈值降噪和双树复小波包重构，即可有效地消除振动信号中噪声的干扰，同时保留信号中的有效信息即实 现了故障特征信息的提取。-In view of the above situation, a new fault diagnosis method is proposed based on dual-tree complex wa
