1. A radio apparatus connectable to a radio control apparatus via a communication link, the radio apparatus comprising:

  • a receiver configured to receive a first signal corresponding to a first communication format and a second signal corresponding to a second communication format, from the radio control apparatus via the communication link;

    a first time-frequency converter configured to convert an I signal and a Q signal of the first signal on a time axis to a first I signal and Q signal on a frequency axis;

    a second time-frequency converter configured to convert an I signal and a Q signal of the second signal on a time axis to a second I signal and Q signal on a frequency axis;

    a combiner configured to combine the first and second signals by deploying and adding the first I signal and Q signal on a frequency axis and the second I signal and Q signal on a frequency axis on a frequency axis and outputs a combined signal including a first frequency corresponding to the first communication format and a second frequency corresponding to the second communication format; and

    an amplifier configured to amplify the combined signal including the first and second frequencies.
