ABSTRACT:
A data transmission apparatus transmits data signals “S1” and “S2” containing identical serial data “ds” in two frequency bands, and a data reception apparatus receives those data signals “S1” and “S2.” Parallel data “dpl” and “dpl2” obtained from the data signals “S1” and “S2” is subjected to selection or synthesis in a subcarrier selection/demodulation circuit so as to be demodulated into serial data “dsx,” which is then outputted to a MAC section.
