Thirdly, in the environment of labview, several kinds of vis used for sensor signal test are designed, including wave generation, time domain measurement, filter disposal, frequency analysis, etc. after that, wavelet analysis in the application of one - dimensional signal de - noise is studied, threshold and translation invariance wavelet de - noise are realized, and wavelet de - noise vi for zero drift signal of the fiber optic gyro in fcs is designed using labview
接著，在labview環境下開發了多種用於傳感器信號測試的虛擬儀器，具有波形發生、時域測量、濾波處理、頻譜分析等多種功能。隨后，研究了小波分析在一維信號消噪中的應用，實現了labview環境下的閾值法和平移不變量法小波消噪，並利用labview設計了飛控系統中光纖陀螺零漂信號的小波消噪儀。 -
Examples of the absoluteness include the principle of invariance for velocity of light, the principle of special relativity, the principle of general relativity, eigenlength, eigentime, minkowski four dimensional space - time
在教學中常常強調其中的」相對」 ，而忽視了相對論中還有「絕對」的一面，如光速不變原理、狹義相對性原理、廣義相對性原理、本徵長度、本徵時間、閔可夫斯基四維時空等都具有絕對性。 -
An algorithm for matching the esprit ' s estimation of two - dimensional angle by using twice svd and once schur is proposed. using two row uniformity sensor - arrays and adding one sensor, the algorithm decomposes the array twice and exploits rotational invariance properties of signal space, so that both angles may be computed via matrix pencil method, and these estimates are automatically paired. simulation results are presented to verify the efficacy of the proposed algorithm
首先針對esprit演算法對窄帶源進行二維doa估計存在測向冗餘的情況，提出了一種改進演算法，該演算法利用子陣信號數據矩陣中包含的信號空間的旋轉不變性質，藉助于矩陣束方法求解出信號的二維到達角，並且利用兩次奇異值及一次schur分解從而實現了esprit二維doa估計參量的自動配對； 2
