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 algorithm?

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 ZF detector?

Traditionally, a ZF detector completely eliminates interference from other symbol layers when detecting a particular symbol layer, which results in suboptimal performance due to noise- enhancement.
