推导了信噪比增益与降采样滤波器权 系数的关系,给出了采用Rayleigh商方法求解给出准则下最优FIR滤波器的方法和步骤。
3) matrix derivative method
矩阵微商法
1.
of B,and presented a method called matrix derivative method to measure the local influence of observation.
考虑增长曲线模型Ｙ＝ＸＢＺ＋ε，ε～Ｎ（０，ＶｎΣｐ，其中Ｙ是ｐ×ｎ阶观察矩阵，Ｘ和Ｚ分别是ｐ×ｍ和ｒ×ｎ阶设计矩阵，Ｂ是ｍ×ｒ阶未知参数阵，Ｖｎ＞０，Σｐ＞０已知，分别是Ｙ的行向量和列向量的公共协方差矩阵；本文用矩阵微商法的思想，讨论了Ｖｎ和Σｐ单独和同时发生扰动时，对未知参数阵Ｂ在ｔｒａｃｅ意义下的最小二乘估计＾Ｂ的影响，给出了相应的影响度量；同时，对于Ｖｎ和Σｐ是某种特殊扰动（如单点扰动）的情形也作了讨论。
