Abstract:
Disclosed is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals that are transmitted in the same frequency bandwidth at the same time. According to the precoding method, one matrix is selected from among matrices defining a precoding process that is performed on the plurality of baseband signals by hopping between the matrices. A first baseband signal and a second baseband signal relating to a first coded block and a second coded block generated by using a predetermined error correction block coding scheme satisfy a given condition.

Claim (Index 3):
A reception device comprising:\n reception circuitry, which in operation, receive signals including two OFDM signals transmitted from different antennas of a transmission apparatus; decoding circuitry, which in operation, decode the receive signals to a transmission data sequence, wherein the two OFDM signals are transmitted from the transmission apparatus through processing including: encoding of the transmission data sequence to the two encoded data sequences; modulation of the two encoded data sequences to two modulated symbol sequences; precoding the two modulated symbol sequences by hopping a precoding matrix expressed by Math. 5 for each symbol to generating two precoded symbol sequences; [ Math . \ue89e 5 ] F \ue8a0 [ i ] = 1 \u03b1 2 + 1 \ue89e ( e j \ue89e \ue89e 0 \u03b1 \u00d7 e j \ue89e \ue89e 0 \u03b1 \u00d7 e j \ue89e \ue89e \u03b8 21 \ue8a0 ( i ) e j \ue8a0 ( \u03b8 21 \ue8a0 ( i ) + \u03c0 ) ) inverse fourier transforming the two precoded symbol sequences to two OFDM signals; and transmission of the two OFDM signals at the same frequency in the same transmission slot from the different antennas, in Math. 5, \u03b1=1, and \u03b8 21  satisfies Math. 6, [ Math . \ue89e 6 ] e j \ue89e \ue89e \u03b8 21 \ue8a0 ( 1 ) e j \ue89e \ue89e \u03b8 21 \ue8a0 ( 0 ) = e j \ue8a0 ( \u03c0 2 ) .
