Q) MIMO-OFDM and freq-domain equalization

Hello, everyone.

In SISO-OFDM, we usually employ a frequency domain equalization after the
receiver FFT module, as a way to compensate for the channel distortion
along frequency bins. We depend on OFDM channel estimation and simple
inversion for this purpose.

In MIMO-OFDM, either multiplexed system or diversity system, what is the
best way to implement a frequency-domain equalization for the MIMO
receiver?

I understand that there are papers about MIMO-FDE for FFT-IFFT-based
single-carrier system. However, as for MIMO-OFDM, I didn't gomf smu
[s[rt/

Can I have some advice, please?
Thank you very much.

The July 2007 IEEE Proceedings lead off with an article on MIMO-OFDM.
