The MIMO channel modeling block and MIMO equalizer block can be used to model 2x2,2x3,3x3,4x4,3x4 or any other combination of Open Loop MIMO system. The blocks can also model SISO and MRC systems. Beamforming using SVD MIMO OFDM is will be supported. The blocks use auto fan-in and auto fan-out to automatically configure themselves based on the number of transmit/receive antennas or receive antennas and spatial streams.

Using the source code as a basis, MIMO equalization algorithms can be developed and tested for performance.
