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.
What is zero forcing solution?
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 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.
