NTT has proposed Variable Polarization Frequency Division Multiplexing (VPFDM) that allows user earth station to free utilize both polarization and frequency resources. However, as the VPFDM system must assign same frequency bandwidth of each polarization, frequency allocation is restricted. To improve frequency utilization, we proposed orthogonal antenna polarization forming against another user / system using common frequency bandwidth. This paper presents digitally polarization forming technique, an overview of developed VPFDM modem with the polarization forming function, measurement results of polarization forming characteristics and dual-polarization frequency sharing transmission experiment via Ku-band communication satellite. Experimental results showed that the developed modem offered desired performance. |
