How does zero forcing work?

The Zero-Forcing Equalizer applies the inverse of the channel frequency response to the received signal, to restore the signal after the channel [21]. The name Zero Forcing corresponds to bringing down the intersymbol interference (ISI) to zero in a noise free case.

What is zero-forcing equalizer algorithm explain?

The zero-forcing equalizer is a form of linear equalization algorithm used in communication systems which applies the inverse of the frequency response of the channel. This form of equalizer was first proposed by Robert Lucky.

What is the use of zero forced equalizers in digital communication?

2.1 Zero Forcing (ZF)

The names zero forcing corresponds to bringing down to inter-symbol interference to zero in a noise free case. This will be useful when ISI is significant compared to noise. Zero-forcing equalizers ignore the additive noise and may significantly amplify noise for channels with spectral nulls.

What is signal equalization?

In telecommunication, equalization is the reversal of distortion incurred by a signal transmitted through a channel. Equalizers are used to render the frequency response—for instance of a telephone line—flat from end-to-end.
