squared value
解釋
均方值-
The traditional bandgap reference circuit was improved in the design, which includes the applying of self - bias structure and cascode structure, output of the opamp was used as self - bias voltage, saving bias circuit, and then it was helpful to get low power consumption. through using poly resistance of high value with low temperature coefficient, we reduced the influnce to circuit, if power supply did not change, we must decrease operating current to decrease power consumption, and increasing value of resistor could decrease the operating current efficiently. poly resistance of high value had large value of squared resistor, so we could save layout area
對傳統帶隙基準電路進行了改進設計，採用自偏置結構和鏡像電流鏡結構，利用運放的輸出電壓作為運放的偏置電壓，節省了偏置電路，降低了功耗;使用低溫度系數的多晶硅高值電阻，降低了電阻溫漂對電路的影響;在電源電壓不變的情況下，為了減小功耗就必須減小工作電流，而增大電阻的阻值能有效地減小工作電流，多晶硅高值電阻的方塊電阻很大，可以節省版圖面積。 -
The variance is simply the average squared difference of all numbers from their mean or average value.
方差就是各個數的中值（或平均值）與各個數的差值的平方的平均值。 -
In order to reduce the deficiencies of ridge estimator, stein shrunken estimator and principal component estimator, two new biased estimators, so - called combining ridge and shrunken estimator, and, combining ridge and principal component estimator, are constructed respectively. their good properties in the mean squared error and the numerical value stability are investigated, the determination of biased parameter of the estimators are discussed, and some important conclusions are obtained, respectively. theory analysis and the computational results demonstrate that the two estimators potential estimator in surveying adjustment
本文針對嶺估計、 stein均勻壓縮估計和主成分估計存在的缺陷，構造了兩種新的有偏估計：嶺?壓縮組合估計和嶺?主成分組合估計，討論了兩種新估計在均方誤差意義下和數值穩定性方面的優良性質，討論了有偏估計中偏參數的選取問題，通過理論分析和算例分析說明這是兩種很有潛力的有偏估計。 -
From simulation results, we get the following main conclusions : 1 ) the convergence performance can be improved with the ist - tap initialization strategy for the underwater acoustic channel established in this paper. 2 ) both the convergence rate and the steady - state value of the average squared error should be taken into account when choosing the step - size
得到的主要結論為：對于本文所建立的水聲多徑通道，盲均衡演算法採用第一個抽頭初始化方案其收斂性能較好；選取迭代步長時要兼顧收斂速度和穩態誤差；在保證收斂性能的基礎上，可選擇階數較小的均衡器。
