S/P transform section 101a transforms transmission data A from serial data into parallel data, and outputs the parallel data to 16 QAM mapping section 102 as data to be mapped onto bits (S0 and S1) with relatively high quality. S/P transform section 101b transforms transmission data B from serial data into parallel data, and outputs the parallel data to 16 QAM mapping section 102 as data to be mapped onto bits (S2 and S3) with relatively low quality. 16 QAM mapping section 102 performs mapping on transmission data A and B on the signal space diagram of 16 QAM by Gray Coding. Then, transmission data A and B undergoes digital modulation, and is transmitted to a communicating party via antenna 105.
