摘要：A coding apparatus capable of preventing deterioration in demodulationperformance without increasing interfering power. In the apparatus, a turbo codingsection () performs turbo coding on transmission data, and outputs systematic bits and

parity bits. A selecting section () selects either of two parity bit sequences output fromthe turbo coding section () to output to a mapping section (-). Another mapping section (-) modulates the systematic bits and performs symbol mapping. The mapping section (-)modulates the parity bits and performs symbol mapping. At this time, mapping sections(-and -) perform modulation in modulation schemes instructed from a modulationscheme instructing section (). The modulation scheme instructed to the mapping section(-) is different from the modulation scheme instructed to another mapping section (-).
