Channel estimation and equalization technique based on ieee 802 . 11 standard 技术及其在无线信道中应用
2 . introduced the adaptive equalization technique into the rss system 2 .将自适应均衡技术引入到再入遥测系统中。
With the development of research , single carrier transmission systems are found with similar equalization techniques and superiorities 随着研究的深入,发现单载波系统也有类似的均衡办法与优点。
With the rapid development of the radio communications , adaptive equalization techniques become the study focus of many engineers 随着无线通信的迅猛发展,自适应均衡技术的研究再次成为人们关注的研究课题。
In this case , blind equalization techniques which need not any training sequence are preferred for underwater acoustic communication 因此,对于水声通信信道,人们更倾向于采用不需要发送训练序列的盲均衡技术。
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训练序列而仅仅利用接收序列就实现均衡的一种新兴的均衡技术。
However , adaptive equalization technique can decrease the effect of isi and noise , reduce the bit error ratio and trace time - changing channel 而自适应均衡技术可以降低码间干扰和噪声的影响,减少误码,并能够跟踪时变信道,解决时变波形的严重失真问题。
Hi this thesis , the characters of the linear fading channel are lucubrated . some effective equalization techniques towards different channel fading are proposed 本课题深入系统地研究了线性衰落信道特性,针对不同的信道衰落,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 介绍一种系统,称为单载波块传输系统,并研究了其各种均衡办法,比较了它们的性能与复杂度。
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 而盲均衡技术可以不用借助训练序列,仅仅根据接收到的信息序列对信道进行自适应均衡,因而引起广泛研究。
