What is zero forcing equalizer 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.
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 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 zero forcing in MIMO?
Zero-forcing (or null-steering) precoding is a method of spatial signal processing by which a multiple antenna transmitter can null the multiuser interference in a multi-user MIMO wireless communication system.
