Abstract
A transmitter transmits data to a communicating opponent with a better channel condition with use of one or more frequency blocks including one or more carrier frequencies. The transmitter includes a communicating opponent selection unit evaluating the channel condition for each frequency block for each of plural communicating opponents and selecting one or more communicating opponents from the plurality of communicating opponents, a modulation scheme determination unit determining at least a modulation scheme depending on the evaluated channel condition, a control channel generation unit generating a control channel indicative of the determined modulation scheme and one or more frequency blocks available for the selected communicating opponents to receive a data channel, and a channel transmission unit providing the selected communicating opponents with the control channel and the data channel modulated in accordance with the modulation scheme.
