Patent ID: 8194786

Claim:
A transmitting apparatus comprising: a selector selecting a configuration from among a plurality of configurations, the plurality of configurations including a first configuration and a second configuration; a signal generator generating a first signal of the first configuration from a first code word and a second signal of the first configuration from a second code word in a case where the selector selects the first configuration, the first code word having attached thereto a first CRC (Cyclic Redundancy Check) and the second code word having attached thereto a second CRC, or generating a first signal and a second signal of the second configuration from the first code word and a third signal of the second configuration from the second code word in a case where the selector selects the second configuration, the first code word having attached thereto the first CRC and the second code word having attached thereto the second CRC; and a transmitter spatially multiplexing and transmitting the first signal and the second signal of the first configuration where the first configuration is selected, or the first signal, the second signal and the third signal of the second configuration where the second configuration is selected, using a plurality of antennas.
