Polarization angle diversity and quick decodable block code for M2M wireless communication

We are developing a 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 distinguish radio waves which are transmitted via different paths. By using new block codes, they can be identify quickly because the block codes don't need any phase locked loop or matched filter. By using a simulation model with five transmission paths, an accuracy of new block codes is shown.
