RADIO TRANSMITTING APPARATUS, RADIO RECEIVING APPARATUS, RADIO TRANSMITTING/RECEIVING SYSTEM, AND METHODS THEREFOR

摘要

A radio transmitting apparatus for transmitting a first radio signal and a second radio signal of different communication schemes includes a first transmitting unit that generates the first radio signal using a first communication scheme and transmits the generated signal, a diffusion processing unit that performs diffusion processing on data assigned to a DC subcarrier using the first communication scheme to generate a diffusion signal, an addition unit that adds the diffusion signal and a signal subjected to orthogonal frequency division multiplex, and a second transmitting unit that transmits the resultant signal obtained by addition as the second radio signal.
