What is zero forcing algorithm in wireless communication?
Zero Forcing Equalizer refers to a form of linear equalization algorithm used in communication systems which applies the inverse of the frequency response of the channel.
What is the main disadvantage of zero forcing equalization?
A serious problem with the zero-forcing equalizer is the noise enhancement, which can result in infinite noise power spectral densities after the equalizer. The noise is enhanced (amplified) at frequencies where the channel has a high attenuation.
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.
Why is zero forcing used?
This is intended to remove the effect of channel from the received signal, in particular the intersymbol interference (ISI). The zero-forcing equalizer removes all ISI, and is ideal when the channel is noiseless.
