Abstract:
Provided is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals to be transmitted over the same frequency bandwidth at the same time, including the steps of selecting a matrix F[i] from among N matrices, which define precoding performed on the plurality of baseband signals, while switching between the N matrices, i being an integer from 0 to N−1, and N being an integer at least two, generating a first precoded signal z 1  and a second precoded signal z 2 , generating a first encoded block and a second encoded block using a predetermined error correction block encoding method, generating a baseband signal with M symbols from the first encoded block and a baseband signal with M symbols the second encoded block, and precoding a combination of the generated baseband signals to generate a precoded signal having M slots.

Claim (Index 4):
A reception device comprising:\n receiving circuitry which, in operation, receives first OFDM symbols transmitted from a first antenna of a transmission system and second OFDM symbols transmitted from a second antenna of the transmission system, wherein the first OFDM symbols includes a plurality of first transmission symbols z 1 , the second OFDM symbols includes a plurality of second transmission symbols z 2 , the plurality of first transmission symbols z 1  and the plurality of second transmission symbols z 2  are generated by, with respect to a plurality of first modulated symbols s 1  and a plurality of second modulated symbols s 2 , using N signal processes for each slot, N being an integer that is at least three, the plurality of first modulated symbols s 1  including one or more first data symbols and one or more first pilot symbols, the plurality of second modulated symbols s 2  including one or more second data symbols and one or more second pilot symbols, the one or more first data symbols being generated with the same transmission data bits as the one or more second data symbols, the N signal processes being regularly switched with N slots as one cycle, and the first OFDM symbols and the second OFDM symbols each include one or more control symbols transmitting control information used in demodulation, the N signal processes being not performed on the one or more control symbols, and demodulating circuitry which, in operation, generates the transmission data bits by demodulating the one or more first data symbols and the one or more second data symbols based on the control information generated by demodulating the one or more control symbols.
