Receiving apparatus, transmitting apparatus, transmission system, receiving method and transmitting method

Abstract

A reception device includes a reception unit that receives a signal obtained by polarization multiplexing of an X polarized wave and a Y polarized wave, converts a received signal into a received signal corresponding to each of the X polarized wave and the Y polarized wave, and outputs the received signal, a first signal decoding unit that decodes one series of transmission signals from the received signal output by the reception unit, a polarization separation unit that performs polarization separation on the received signal corresponding to each of the X polarized wave and the Y polarized wave and output by the reception unit, a second signal decoding unit that decodes the received signal polarization-separated by the polarization separation unit, and a first polarization processing switching unit that captures a received signal corresponding to each of the X polarized wave and the Y polarized wave and output by the reception unit, and switches an output destination of the received signal that has been captured to one of the first signal decoding unit and the polarization separation unit on the basis of information indicating a modulation method.
