What is equalization in OFDM?

The OFDM Equalizer block equalizes the OFDM data using channel estimates. The block supports zero-forcing (ZF) and minimum mean square error (MMSE) algorithms for channel equalization in the frequency domain.

What is channel estimation and Equalization?

Channel estimation provides information about distortion of the transmission signal when it propagates through the channel. This information is then used by equalizers so that the fading effect and/or co-channel interference can be removed and the original transmitted signal can be restored.
