dual circular polarization

hai,

I'm in need of knowing the definition of dual circular polarization and I want to simulate 4x4 MIMO over satellite systems.

My aim is to find BER,capacity and more specifically the co polarization and cross polarization for both right hand and left hand polarization.

The parameters that you mention can be extracted out from the final step of MATLAB simulations. But first, you will need to generate the antennas' performance for co-pol and cross-pol in an EM software.
