Abstract: If any waveform software to be used is determined without taking into account the status of the other end of communication, the communication with the other end may possibly fail. Each of a plurality of radio devices observes its status, which dynamically varies in relation to that radio device, and transmits observation data, i.e., data representative of the observed status to a server apparatus. The server apparatus receives the observation data transmitted from the radio devices. Further, the server apparatus determines, on the basis of the observation data received from the radio devices, waveform software to be used for communications between or among the radio devices, and transmits the determined waveform software to the radio devices. Each of the radio devices receives the waveform software transmitted from the server apparatus and uses the received waveform software to control its own software radio communication means.

Abstract: A transmission apparatus is provided with: a plurality of amplification units that amplify RF signals arranged in at least 2 bands; a first control unit that selects amplification units that perform an amplification operation, from among the plurality of amplification units, in accordance with total power of RF signals to be transmitted; a second control unit which, in accordance with a power ratio of the RF signals to be transmitted in respective bands, changes the power ratio of the RF signals in the respective bands while keeping constant the total power of the RF signals received at each of the selected amplification units; and a combining unit that combines the RF signals outputted by the selected amplification units.
