PURPOSE:To easily confirm step out, by performing modulation after code conversion is applied on a prescribed modulation unit on which a dummy bit is added, to discriminate the modulation unit on which the dummy bit is added out of plural multi-dimensional modulation units sandwiched between adjacent frame signals. CONSTITUTION:In step S1, a transmission data is made into a random form, and after that, the plural modulated shares of transmission data are accumulated synchronously with a frame signal, and after the dummy bit is added on and a prescribed time adjustment is performed, the code conversion is applied on a prescribed modulation unit in a frame unit in step S3. Thus, the data on which the code conversion is applied in step S3 is multi-dimensional-modulated in step S4, and it is transferred to a reception side in step 55. At the reception side, the said signal, after being multi-dimensional-demodulated, is code converted, and is taken out as a reception data. |
