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.

What is equalizer in OFDM?

The OFDM Equalizer block supports ZF and MMSE algorithms for channel equalization in the frequency domain. The block stores the estimated channel information to equalize the OFDM symbols and generates the equalized output using these algorithms.
