<p>A setting unit (4) determines basic information on a modulation method, a coding ratio, and a puncturing rule besed on a quality signal at each base station (5) that is measured at a mobile station (12). A transmission control unit (6) of each base station (5) determines the modulation method, the coding ratio, and the puncturing rule for each of the base stations (5) according to the basic information and the signal quality of each base station (5). Based on this determination, a code selection unit (7) executes puncturing, an interleave unit (8) executes interleawe, and a modulation unit (9) executes modulation. In the mobile station (12), based on the modulation method, the coding ratio, and the puncturing rule included in a control signal from each base station, a demodulation unit (15) executes a demodulation processing, a deinterleave unit (16) executes a deinterleave processing, and a code combining unit (17) executes code combining. <IMAGE></p> |
