MIMO MMSE Estimator
This functionality is available only within the Intel® System Studio suite.
The MIMO MMSE is based on the output of FFT (
y
) and channel estimation (H
).
The figure below shows the system model used for the MMSE estimation per subcarrier.

According to this figure, the basic equation is
y
=H
*x
+n
where

- Nris the number of receive antennas (2, 4, or 8)
- Ntis the number of transmit antennas (1 or 2)
- xis the data frequency domain symbol
