A Polarized OFDM (POFDM) scheme is proposed for the wireless depolarized channel. Through such scheme, each sub-carrier's polarization state, amplitude and phase can be modulated to bear information, and the spectrum efficiency can be further improved. Consider the multi-path fading channel, the channel caused depolarization impairments to POFDM are quantitatively analyzed; to mitigate such impairments,...
A Polarized Phase Shifting Keying/Quadrature Amplitude Modulation(PPSK/PQAM) scheme in the wireless depolarized channel is proposed. Such scheme uses the carrier's polarization state, amplitude and phase as the information bearing parameters, and can further improve the traditional modulation methods' spectrum efficiency. The impairment to PPSK/PQAM from the wireless depolarized channel is quantitatively...
