Help regarding Freq Domain Equalizer?

[bee]

Can any one plz explain me what Freq Domain Equalizers are and how they work?

Waiting

of course this is for the Frequency Domain Equalizer in Simulink, but still you will get an idea of what they do.

The underlying philosophy of both time domain and frequency domain equalizers are the same - to equalize the channel frequency response, but the latter achieves the job in the frequency domain.

In a frequency domain equalized system the reference signal (pilot) is usually sent in the frequency domain and is used to estimate the channel frequency response, which in turn will be used to equalize the received data.
But, in a Time domain equalized system the pilot will be sent in the time domain and the Channel Impulse response will be estimated and used to equalize the received data

time domain equalization: equalize in the time domain, by cofficients.

freq domain equalization: transform to freq domain first, then equalize, at last change back to time domain
