What is MMSE equalizer?
MMSE as an Equalizer is a kind of post processing algorithm that helps us to figure out the received data that is as close to the original data (transmitted data) as possible. In short, the most important steps in MMSE is to find a matrix G in the following illustration.
Why is it called zero forcing?
The name Zero Forcing corresponds to bringing down the intersymbol interference (ISI) to zero in a noise free case. This will be useful when ISI is significant compared to noise.
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 equalization technique in wireless communication?
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.
