We report the results of satellite experiments on Variable Polarization/Frequency Division Multiplexing (VPFDM) and its operational principles. VPFDM is a new multiple access method that enables each user to freely utilize dual polarization and frequency resources. No BER degradation was observed in VPFDM satellite experiments, meaning that the VPFDM modem can demodulate received signals as expected regardless of the polarization rotation angle or dynamic polarization rotation. Because of this performance, we expect VPFDM to be applied to the maritime satellite communications service called Earth Station onboard Vessel (ESV)[l][2], to which Ku band is allotted as a primary band in the WRC 2003.
