Claim Text:
1. A transmission device for performing multiple-input multiple-output (MIMO) transmission, comprising: an error correction coding circuit that performs error correction coding on a basic transmit data string pertaining to basic information and performs error correction coding on an extended transmit data string pertaining to extended information; a mapping circuit that maps a basic error correction coded data string to symbols, the basic error correction coded data string being based on the error correction coding of the basic transmit data string, and maps an extended error correction coded data string to symbols, the extended error correction coded data string being based on the error correction coding of the extended transmit data string; and a MIMO coding circuit that performs MIMO coding on a basic mapping data string, the basic mapping data string being based on the mapping of the basic error correction coded data string, and performs MIMO coding on an extended mapping data string, the extended mapping data string being based on the mapping of the extended error correction coded data string, wherein the basic information is transmitted by MIMO, using a single fundamental band, after the error correction coding, the mapping, and the MIMO coding, the extended information is transmitted by MIMO, using a plurality of fundamental bands, after the error correction coding, the mapping, and the MIMO coding, the plurality of fundamental bands including the single fundamental band, the basic information is independently decodable, and the extended information is decodable when combined with the basic information.
