Abstract:
This signal processing device comprises: an acquisition unit that acquires identification information for data outputted to a later-stage processing unit, the data being obtained by decoding a reception signal on which a signal from another layer is superimposed in the power-axis direction of the signal of a first layer; a decoding unit that, after the signal from the first layer is decoded, decodes the signal from the other layer on the basis of the result of the decoding of the signal from the first layer; and an output control unit that outputs, to the later-stage processing unit, the data obtained by decoding the signal of the other layer, without outputting the data obtained by decoding the signal from the first layer to the later-stage processing unit, when the data specified in the identification information is data that is obtained by decoding the signal from the other layer.
