| 摘要 |
<p>PROBLEM TO BE SOLVED: To provide a transmitter that transmits data streams including at least 1st and 2nd data streams by modulating carriers whose frequencies are in an orthogonal relation. SOLUTION: An output of a 2nd error correction coding section corresponding to the 2nd data stream and the 1st data stream are modulated and the modulation output is subjected to inverse Fourier transform processing. An output signal from the inverse Fourier transform section consists of symbol signals and guard signals. The transmitter selects one period of ha symbol signal among a plurality of kinds of periods.</p> |
