求翻譯：由于信道的不理想，再加上存在噪聲，接收濾波器收到的波形與發(fā)送端發(fā)出的波形可能差別比較大，如果馬上進行判決，可能產(chǎn)生較多的誤碼，因此，在取樣判決之前需先經(jīng)過一個接收濾波器，一方面濾除帶外噪聲，提高信噪比，另一方面對失真的波形進行均衡，因此，接收濾波器中還應(yīng)包括均衡器在內(nèi)，以便得到有利于取樣判決的波形是什么意思？ 待解決

As the channel is not ideal, coupled with the presence of noise, the receiver filter and the transmitter waveform received waveform may be issued by relatively large differences, if immediate decision, may produce more errors, therefore, required before the sample sentence go through a receiver filt

Because the channel is not ideal, in addition has the noise, the profile possible difference which receives which the filter to receive the profile and the transmitting end send out quite to be big, if carries on the decision immediately, possibly has many error codes, therefore, before sample decis

Due to channel of does not ideal, then plus exists noise, received filter received of waveform and sent end issued of waveform may differences comparison large, if immediately for judgment, may produced more of error, therefore, in sampling judgment zhiqian needed first after a received filter, whil

Because channel unsatisfactory, in addition, exist noise, receive wave form that electric-wave filter receive and it sends wave forms that ends sends out to be perhaps difference relatively l
