Abstract

To improve Power Amplifier (PA) energy efficiency, a Polarization Modulation (PM) scheme in wireless communication is proposed. The proposed scheme uses polarization state as the information-bearing parameter and can let the PA work in its nonlinear region without suffering distortion. Furthermore, to mitigate the impairment to the PM from the polarization dependent loss effect of the wireless channel, an optimal pre-compensation algorithm is also presented. Simulations under the same symbol error rate show the PM can improve the PA energy efficiency by 25% at most compared with the phase shifting keying.
