Abstract :
The next generation of digital terrestrial broadcasting systems using dual-polarized SDM-MIMO technology is under development. The reception deteriorates under an AWGN channel when the XPD for the SDM-MIMO system is low. We describe a method for inter-polarization spreading in the SDM-MIMO transmission system that compensates for the deterioration and our investigation of the reception in a computer simulation. The simulation results show that applying the spreading can improve the reception in an AWGN and in TU6 channels. They also show that the reception was even improved when using a single receiving antenna.
