<P>PROBLEM TO BE SOLVED: To provide a digital radio communication device capable of reducing the deterioration of communication quality and throughput in a multipath fading environment. <P>SOLUTION: A digital radio communication device performs communication by adaptively selecting a desired modulation class from a plurality of modulation classes composed of the set of a modulation scheme and a coding rate. The digital radio communication device includes: a modulation class decision unit 533 for selecting the modulation class of the next transmission data, on the basis of the own quality information related to the own reception quality on a transmission signal from the self-device included in a reception signal from an opposite communication device; based on the reception signal, mating quality information generation units (512, 514, 516, 531, 532) for generating mating quality information related to the mating reception quality on the opposite communication device; and to transmit the mating quality information to the opposite communication device, a modulation processing unit 534 for modulating the mating quality information by the modulation scheme of the modulation class selected by the modulation class decision unit 533. <P>COPYRIGHT: (C)2013,JPO&INPIT |
