Application of polarization modulation in satellite communication

Based on the analysis of electromagnetic wave polarization characteristics, the polarization modulation (PM) scheme is proposed and the PM transceiver is designed in the satellite communication in this paper. The symbol error rate of the polarization modulation is deduced and verified by the Monte Carlo simulation in the AWGN channel. It is proven that the polarization modulation does not require accurate carrier synchronization and transmit signals are immune to nonlinearity of the high power amplifier(HPA). Comparing with the DPSK non-coherent demodulation, PM scheme is more suitable in no carrier recovery systems, such as high frequency narrow-band or high dynamic satellite communication.
