Polarization angle diversity and new digital software radio architecture

We are developing new radio architecture for applying a wireless communication system to controlling and monitoring systems in industrial infrastructure systems. Using polarization angle diversity, we can achieve reliable communication in a non line-of-sight situation. To realize polarization angle diversity, we use a rotating polarized radio wave. When we use polarization angle diversity, we need to control radio frequencies more easily. New software radio architecture create radio frequency in a digital circuit directly. It has a possibility to control a rotating polarization radio wave. And by experiment, I show a result of basic communication test and confirm its functions.
