极限情况下,当混叠十分严重时,相对于理想低通滤波器,用维纳滤波器进行亚象素插值能将预测残差均方和减少一半。
In an extreme case, when the aliasing effects are very severe, using wiener filter can reduce the prediction errors'energy by about 50% in comparison with using the ideal low pass filter.
研究这一估计的性质,证明利用0-K型广义岭估计技术可以改进广义岭估计(在均方残差意义下)。
The 0-K class of estimators if studied, it will be proved that under the mean square residua criterion the estimators can be improved via the generalized ridge regression technique.
