What are taps in equalizer?
A delay element is often called a tap, but a tap also can be considered the combination of a delay element, the point where some of the signal is “tapped” off, and a multiplier. The boxes labeled b-2, b-1, b0, etc., are multipliers with equalization coefficients that set the gain for each tap.
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.
