<p>A communication apparatus transmits data by adaptively selecting at least one of an error-correction coding rate and a modulation method so that the error rate of data transmission is within a target error rate at a destination. In the communication apparatus, a transmission-parameter generating unit selects at least one of an error-correction coding rate and a modulation method based on the number of hops, transmission channel characteristics, and the target error rate, thus generating at least one transmission parameter, and an error-correction coding unit and a modulating unit adaptively perform either or both error-correction coding and modulation according to the transmission parameter.</p> |
