because blind channel equalizer can reduce the intersymbol interference without the assistance of the transmitted sequence, it has been becoming a very popular research topic in recent years.
盲均衡器由于不需要训练序列,仅利用接收信号的统计特性就能对信道特性进行均衡,消除码间串扰,成为近年来通信领域研究的热点课题。
this means that the intersymbol interference caused by channel aberration and multipath becomes more serious.
这就意味着信道畸变和多径效应产生的码间干扰更严重。
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。
