PROBLEM TO BE SOLVED: To reduce the number of RF processing circuits at transmitting of data to each terminal of two terminals by using radio waves with the same frequency with the same timing. SOLUTION: This device is provided with a fist circuit 100 for preparing a first modulated signal by operating weighting processing and modulation processing to first transmission data, a second circuit 200 for preparing a second modulated signal by conducting weighting processing and modulation processing to second transmission data, an adder 300 for preparing an added modulated signal by adding the first modulated signal and the second modulated signal, a digital/analog converter(DAC) 400 for converting the added modulated signal into an analog signal, a high frequency (RF) processing circuit 500 for preparing a transmission signal by superposing the analog signal on carrier frequencies, and an antenna 600 for outputting the transmission signal. |
