In satellite communications both polarizations of an electromagnetic wave are used to transmit two separate signals. These two independent signals can be merged to form one dual-polarization, four-dimensional signal. The present article pursues this idea and proposes different signal constellations to be used for four-dimensional signalling in satellite(More)
Polarization Shift Keying is a digital modulation method using the state of polarization of an electromagnetic wave as the signalling quantity. The technique comes from fibre communications, where the channel offers two orthogonal states of polarization. This paper develops on the idea to adapt this technology to satellite communications, where comparable(More)
