释义 |
1 [数]?误差向量 ...模型的必要性:假设未 经量化的特征向量是 V,V 经过特征向量 量化后得到的新特征向量是 V’,又量化 的误差向量(Error Vector)记做n, 则 V = V’ + n , 即 V’ = V - n , 此时 V’就好比是干净的特征向量加 上一个杂讯 n,因此若我们想要辨识一个 被杂... 2 ?错误向量 ...eal Signal)还原,由所还原的瞬间理想向量(Ideal Vector)所指向量测向量(Measured Vector)的向量,就叫作错误向量(Error Vector),如所示,错误向量的振幅,除以理想向量的振幅所得出的比例值就称为EVM,以百分比表示之。 3 ?误差矢量 3.3误差矢量(error vector):等于测量到的矢量与参考矢量的矢量差。
