<P>PROBLEM TO BE SOLVED: To provide an optical wireless communication device for selecting the optimum transmission method in which high transmission efficiency is secured even when mutual positional relation between terminals is changed. <P>SOLUTION: In the optical wireless communication device, the first terminal includes a transmission signal control section, a plurality of optical transmission sections, and a feedback reception section. The second terminal includes a plurality of optical reception sections, a signal detection section, and a feedback transmission section. The transmission signal control section changes over whether a plurality of optical transmission sections transmits mutually different signals or transmits the mutually same signals, on the basis of the feedback signal indicating the reception states of a plurality of transmission optical signals. <P>COPYRIGHT: (C)2011,JPO&INPIT |
