Signal processing device, signal processing method, reception device, and signal processing program

A reception device comprising:

• a reception processing unit that outputs, to a post-stage processing unit, data obtained by decoding a reception signal that includes a signal included in a first layer and a signal included in a different layer and superimposed on the signal of the first layer in a power axis direction, wherein
• the reception processing unit includes
• an acquisition unit that acquires identification information associated with the data output to the post-stage processing unit,
• a decoding unit that decodes the signal of the different layer on a basis of a result of decoding of the signal of the first layer after the decoding of the signal of the first layer, and
• an output control unit that outputs data obtained by decoding the signal of the different layer to the post-stage processing unit without outputting data obtained by decoding the signal of the first layer to the post-stage processing unit, in a case where data identified by the identification information is data obtained by decoding the signal of the different layer.

A signal processing method comprising:

• acquiring identification information associated with data obtained by decoding a reception signal that includes a signal included in a first layer and a signal included in a different layer and superimposed on the signal of the first layer in a power axis direction, the data being output to a post-stage processing unit;
• decoding the signal of the different layer on a basis of a result of decoding of the signal of the first layer after the decoding of the signal of the first layer;
• and
• outputting data obtained by decoding the signal of the different layer to the post-stage processing unit without outputting data obtained by decoding the signal of the first layer to the post-stage processing unit, in a case where data identified by the identification information is data obtained by decoding the signal of the different layer.

A signal processing program for causing a computer to function as:

• an acquisition unit that acquires identification information associated with data obtained by decoding a reception signal that includes a signal included in a first layer and a signal included in a different layer and superimposed on the signal of the first layer in a power axis direction, the data being output to a post-stage processing unit;
• a decoding unit that decodes the signal of the different layer on a basis of a result of decoding of the signal of the first layer after the decoding of the signal of the first layer;
• and
• an output control unit that outputs data obtained by decoding the signal of the different layer to the post-stage processing unit without outputting data obtained by decoding the signal of the first layer to the post-stage processing unit, in a case where data identified by the identification information is data obtained by decoding the signal of the different layer.
