A new approach to equalization of linear single - input single - output time - selective fading channel 時間選擇性衰落信道迫零均衡新方法
This paper builds the small - signal model of the ml converter , and decouples the converter into several independent single - input single - output systems with the control strategy proposed in [ 8 ] , so the closed - loops for the output voltage and the flying capacitor voltages can be designed independently 本文首先建立了buck多電平變換器的小信號模型,并利用文獻[ 8 ]提出的控制方法將該變換器解耦成多個單輸入單輸出系統(tǒng)。
First , in view of the basic theory for fuzzy control , this section mainly discusses the interpolation nature of single - input single - output and double - input single - output mamdani algorithm , and explains the basic idea of fuzzy interpolation , in which the number of control rules can be reduced , improving the calculating speed of fuzzy controller 首先,在模糊控制基本理論基礎上,重點對單輸入單輸出和雙輸入單輸出mamdani算法的插值機理進行了論述,闡述了模糊插值的基本思想,通過模糊插值來減少規(guī)則的數(shù)量,提高了模糊控制器的計算速度。
All of those antennas are measured and have good results . first , the research background is reviewed , the development and defects of the current mobile communication systems are summarized and the inevitability of using mimo technologies is discussed . then this dissertation systematically expatiates on mimo technologies , including the evolution of the traditional single - input single - output 首先,本文簡要回顧了研究的相關背景,通過對現(xiàn)代移動通信的發(fā)展及其所面臨的挑戰(zhàn)和急需解決的問題的總結,了解了mimo通信技術引入的必然性;在此基礎上,對mimo移動通信技術進行了系統(tǒng)的闡述,包括傳統(tǒng)的siso系統(tǒng)以及智能天線系統(tǒng)向mimo系統(tǒng)的演進, mimo移動通信技術基本原理, mimo系統(tǒng)的主要研究內容和國內外研究動態(tài)。
