I'm asking about the difference about channel shortening and time-domain equalization. I have checked on-line and tried to get something clear but I couldn't.

What I found is that channel shortening means almost "Calculating the coefficients for DFE equalizer" But I couldn't also imagine that.

Could you please explain.

Thank you

    $\begingroup$ By "time equalization" do you mean "time-domain equalization"? It would be good if you gave references where you found the terms you ask about. "Channel shortening" is clear but "time equalization" isn't. $\endgroup$ – Matt L. Aug 14 '18 at 11:37
  • $\begingroup$ @MattL. .. Yes It's time-domain equalization $\endgroup$ – New_student Aug 14 '18 at 16:43
  • $\begingroup$ @Eng.Badr it's really not the first time we ask you to cite your sources. :( This question is unclear without you telling us where you've found these terms. $\endgroup$ – Marcus Müller Aug 14 '18 at 17:47
  • $\begingroup$ @MarcusMüller It's strange that you ask such questions like that !!!! You don't know neither what's the time-domain equalization nor what's the channel shortening ?? Dear,, these concepts are the basic of communications eng. .. just google them and read .... !!! .. So, again you downvoted !! These terms are found everywhere dear. $\endgroup$ – New_student Aug 15 '18 at 2:48
  • $\begingroup$ Not discussing this with you. Cite your sources when writing "I found...". It's really not optional. $\endgroup$ – Marcus Müller Aug 15 '18 at 6:02

Yes,I agreed these terms are very common in communication engineering,

I was asking about channel shortening long time ago, and I got an answer telling me that channel shortening is just calculating the coefficients of the DFE. you can read the details in the below link

Channel Shortening for underwater acoustic channel communication

thanks

  • $\begingroup$ Thank you . I got it, but I still search what's the difference between them ? why do we call sometimes channel shortening and another time TEQ ? $\endgroup$ – New_student Aug 15 '18 at 6:32
