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。
Adaptive equalization technology has been regarded as a potential candidate to combat isi for future wireless communications 在新一代无线通信系统中,自适应均衡技术,被认为是最有可能采用克服码间干扰的方案。
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。
Finally , a new approach combining equalization and adaptive equalization with ldpc decoding are proposed to combat the intersymbol interference ( isi ) and channel noise 最后,针对噪声干扰和码间串扰问题,研究了ldpc码组合均衡技术以及组合自适应均衡技术。
The adaptive equalization is just the main method of eliminating isi , and its theory is to equalize the characteristic of the communication channel or the whole communication system 而自适应均衡技术正是消除isi的主要方法,其机理是对信道或整个传输系统特性进行补偿。
