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(cè)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(diǎn)。
With the rapid development of the radio communications , adaptive equalization techniques become the study focus of many engineers 隨著無(wú)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(duì)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(shí)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(shí)變信道,解決時(shí)變波形的嚴(yán)重失真問(wèn)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(duì)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(duì)信道進(jìn)行自適應(yīng)均衡,因而引起廣泛研究。
