dual circular polarization

hai,

I'm in need of knowing the definition of dual circular polarization

- dual circular polarization means that your antenna system can receive both types of circular polarization. Crossed dipole/yagi antennas are a possible solution. Spiral antennas are also commonly used to achieve circular polarization.

and I want to simulate 4x4 MIMO over satellite systems.

- MIMO system simulation normally involve two different parts. First, you need to characterize your Tx and Rx antennas (most probably in some EM software, like HFSS/CST/FEKO/ADS-Momentum). After that, MATLAB is often used to set up the environment, channel, transfer function etc...

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