Numeric - symbolic technique is introduced in the procedure of resultant elimination, procedure of number - spobol manipulation is transformed into that of matrix manipulation. because joini variables are treated as symbols and all structure paramcters are treated as real nuxnbers, the complexity of derivation for input - output equaion is reduced. the soluton is verified with a numerical example, its rsults withoot extraneous roots agree with the original equaions
消元過程中引入了數字-符號方法,將結構參數處理為數值量,將關節變量處理為符號量,將數字、符號推導過程轉化為了矩陣運算過程,由於結構參數以數值量的形式出現在方程推導中,降低了符號推導的難度,符號推導不需要復雜的符號處理軟體的支持。Based on piecewise linear model, this paper proposes an estimation method that first estimates the slope of linear variant and the channel impulse response at the middle time of the current ofdm symbol using pilot sequences, and then estimates the whole channel impulse response through the estimated parameters
該演算法首先利用導頻序列估計出當前ofdm符號間隔內通道線性變化的斜率和中間時刻通道的沖激響應值,然後根據線性模型利用估計出的參數得到當前符號間隔內所有時刻上的通道沖激響應。In order to do this, a chaotic system is designed, in which, one of the unknown parameters is the measured value or parameter being estimated. between the parameter and the symbolic series corresponding to chaotic orbits of the system output, there should be a homologous relationship
基本思想是設法構造一個混沌系統,將被測量或待估的參數作為系統中的某一未知參數,並在該參數與系統輸出的混沌軌道對應的符號序列之間建立起一一對應關系,用符號空間的距離測度來表示參數的變化。According to the research of the medium - voltage power line transmission characteristics and frequency - domain modeling of bottom up mode that is to accquire characteristic parameters by theoretical calculation, the characteristic modeling of medium - voltage power line is established, and the suitable parameters which can restrain the signal attenuation is gained
本文首先通過對中壓電力線傳輸特性的研究,利用從下往上的頻域研究模式,即通過理論計算獲得特徵參數,建立了中壓電力線傳輸通道特性模型,推出了符合中壓電力線傳輸函數變化的參數,可以有效地抑制信號衰減。Second, by combining theories of strength of laminate with ga, a new gradient free optimization method with new code strategy is discussed. the representation itself does not change the nature of the problem, but effects the searching efficiency of the algorithm. so the representation of the parameters to be optimized is a very important factor and the new code strategy is also easy used with crossover operator and variation operator in ga applications
其次,本文根據層合板優化設計的具體問題提出了一種符號編碼方式,雖然優化參數的基因編碼表達方式並不能改變優化問題的本質,但是不同的編碼表達方式對于遺傳演算法搜索的效率和最終的優化結果有著重要的影響,因此優化參數的基因編碼表達是遺傳演算法應用於工程問題中非常關鍵的一步。By using the solutions of a new auxiliary elliptic equation, a direct algebraic method is proposed to construct the exact solutions of some nonlinear evolution equations. the main difference between this method and previous auxiliary elliptic equation methods is that the balance order becomes smaller after using the new auxiliary elliptic equation. therefore, the derived algebraic equations are greatly simplified. meanwhile, the obtained new solutions contain more parameters to be chosen. for some special cases, they give the previous known solutions. it is shown that some new exact periodic solutions of some nonlinear evolution equations are explicitly obtained with the aid of symbolic computation
利用一個新的輔助橢圓方程將求解非線性發展方程精確解的問題轉化為一個代數方程組進行求解,與已有的輔助橢圓方程法的主要不同是,應用這一新的輔助橢圓方程后降低了平衡次數,減少了所得的代數方程組的個數和方程的項數,從而大大地簡化了代數方程組的求解.同時,由於輔助橢圓方程的解中包含了更多的可選參數,從而給出了非線性發展方程的更多形式的解.作為應用,藉助于計算機的符號計算,求得了一些非線性發展方程的新的精確周期解Because graphical languages still must provide symbols to the computer for compilation or interpretation, graphical specifications are still be required to follow formal language parameters
由於圖形化語言仍然必須向計算機提供符號來進行編譯和解釋,因此我們需要採用圖形化規范來限定形式語言的參數。分享友人
