2 . introduced the adaptive equalization technique into the rss system 2 .將自適應(yīng)均衡技術(shù)引入到再入遙測系統(tǒng)中。
With the development of research , single carrier transmission systems are found with similar equalization techniques and superiorities 隨著研究的深入,發(fā)現(xiàn)單載波系統(tǒng)也有類似的均衡辦法與優(yōu)點。
With the rapid development of the radio communications , adaptive equalization techniques become the study focus of many engineers 隨著無線通信的迅猛發(fā)展,自適應(yīng)均衡技術(shù)的研究再次成為人們關(guān)注的研究課題。
In this case , blind equalization techniques which need not any training sequence are preferred for underwater acoustic communication 因此,對于水聲通信信道,人們更傾向于采用不需要發(fā)送訓(xùn)練序列的盲均衡技術(shù)。
Blind equalization techniques rely on solely the received channel output signal to adjust the equalizer weights without a known training sequence available 盲均衡就是不借助于訓(xùn)練序列而僅僅利用接收序列就實現(xiàn)均衡的一種新興的均衡技術(shù)。
However , adaptive equalization technique can decrease the effect of isi and noise , reduce the bit error ratio and trace time - changing channel 而自適應(yīng)均衡技術(shù)可以降低碼間干擾和噪聲的影響,減少誤碼,并能夠跟蹤時變信道,解決時變波形的嚴重失真問題。
Hi this thesis , the characters of the linear fading channel are lucubrated . some effective equalization techniques towards different channel fading are proposed 本課題深入系統(tǒng)地研究了線性衰落信道特性,針對不同的信道衰落,提出一些有效的均衡方法。
A new system , named single carrier block transmission system , is introduced , variable equalization techniques are developed and the performance and complexities are compared 介紹一種系統(tǒng),稱為單載波塊傳輸系統(tǒng),并研究了其各種均衡辦法,比較了它們的性能與復(fù)雜度。
In addition , sometimes it is impossible to transmit training sequence . however blind equalization technique can depend on only the received data sequence to equalize the channels 而盲均衡技術(shù)可以不用借助訓(xùn)練序列,僅僅根據(jù)接收到的信息序列對信道進行自適應(yīng)均衡,因而引起廣泛研究。
