對于亞穩的-位相態，我們利用瞬子技術計算了它的衰變率或壽命。The following algorithms have been proposed and tested in the thesis : 1 frequency selective fading : combine the isomorphism between the input space and the output space and propose a new approach to blind equalization of the channel. compared with conventional methods, the new approach offers lower computational complexity, better performance, and more robust against the over - determination of the system order ; 2 time selective fading : a new approach to the equalization of time selective channel based on the zero - forced equalizer is proposed which is more simple in its structure of algorithm ; 3 time - varying channel : using the instantaneous mean value changes of the output signal to extract the information of channel variations and model it using ar model, kalman filter is then employed to track channel variations, it bears faster ability in tracking the variation of tv channels ; based on the isomorphism between the inputs and the outputs and some of the approaches using in mimo system, a new algorithm of equalization of simo time - varying channel is proposed, which also share the merits of being robust against the over - determination of the system order ; model the time - varying channel using the multi - resolution decomposition wavelets, and then a blind identification method based " on the model is proposed ; at last, a new model for equalization and identification of mimo system is proposed
主要工作在以下幾個方面： 1 、針對頻率選擇性衰落通道：結合輸入輸出空間同構關系提出一種新的頻率選擇性通道均衡方法，與傳統方法相比，該方法計算量更小，收斂速度更快，性能更優，且對系統階次的過確定表現穩健，具有實際均衡應用價值； 2 、針對時間選擇性衰落通道：提出一種基於迫零均衡的時間選擇性通道均衡方法，演算法結構簡單； 3 、針對時變色散通道：利用瞬態均值曲線提取通道時變信息，對之ar建模，利用卡爾曼濾波器跟蹤時變通道抽頭變化，可以快速跟蹤通道變化；基於輸入輸出空間之間的同構關系以及多輸入多輸出系統的處理方法，提出了新的單輸入多輸出色散時變通道均衡與識別演算法，同樣具有對通道階次過確定保持穩健的優點；結合小波多解析度分析提出一種基於小波模型的通道盲識別演算法；研究時變的多輸入多輸出系統的盲均衡與盲反卷積問題，給出一種時變系統處理模型。A lumped parameter model was developed for predicting the transient motion of mirrors, taking into account electrostatic and tensile forces and viscous air damping via squeeze film theory
考慮靜電驅動力、張力和空氣阻尼衰減對變形鏡回復過程的影響，建立一種復合參數模型來預測變形鏡的瞬態行為。According to the electromagnetic induction theory, abrupt variation of current in the transmitter loop will induce magnetic field around it, which is called the first field. in the transmission of the first field, when it meets good conductor target, induce current will be created, which is called erratic current of second current. because the second current changes with time, so it will create new magnetic field, which is called
對于接收部分，由於瞬變信號具有早期信號幅度大、衰減快，而中晚期信號幅度小、衰減慢的大動態范圍的特點，必須設計適應這種大動態范圍信號的採集電路;為了適應野外工作，系統主控部分採用具有功耗低、高速處理的dsp ，通過高速通用串列介面usb與上位機通訊，實現對整個探測系統的控制。As we know, the experimentally observed result is the prompt j / production, which include the direct j / production, the decay of and the radiative feedown of xcj
我們知道，實驗觀測得到的是瞬態j w產生，即包含有直接j w的產生。 w和l 。的衰變貢獻。分享友人
