FIELD: information technology. ^ SUBSTANCE: in a radio transmitting device (100), the part (113) for solving the ratio repetition/total structures controls the number of constellation diagrams to be used by the modulating part (102), and also controls the number of copies of the repetition part (103) such that, the product of the number of total structures to be used by the modulating part (102), specifically the number of characters sent, which are subject to generation, and the number of characters sent, which are duplicated by the repetition part (103), is equal to the number of characters sent, which are generated from one-off transmission data from the control information extraction part (112). ^ EFFECT: gaining from diversity in the frequency domain. ^ 8 cl, 8 dwg |
