Consider we know that our medium is dispersive and we are transmitting/expecting a signal around 10kHz at receiver, as we do not get only 10 kHz, the input has a sligh spread as well. Due to dispersive medium the 10kHz frequicies has a small spread. The question: Is there filter a which can undo the spread, in other words transfer the energy in bands close to 10 kHz to 10 kHz?

Any suggesetion help would be appreciated.

  • $\begingroup$ @Pier-YvesLessard, I am afraid not, as I am not considering window effect, althogh the affect looks similar. $\endgroup$ – Creator Jun 26 at 21:23
  • $\begingroup$ Right, do you need to process this in real time? What information are you trying to obtain in the end? Would a simple passband feeding a power estimation algorithm be enough? $\endgroup$ – Pier-Yves Lessard Jun 26 at 21:26
  • $\begingroup$ @Pier-YvesLessard. yes almost real time and pass band only fails. I want as much energy as possible near central frequency. $\endgroup$ – Creator Jun 26 at 21:27
  • $\begingroup$ I think you should edit your question and elaborate a little more on what you try to achieve at a higher level as well as what you did and why it is not enough. It is hard to help otherwise $\endgroup$ – Pier-Yves Lessard Jun 26 at 21:29
