Optical wireless transmitter, optical wireless receiver, and optical wireless communication system

摘要

PROBLEM TO BE SOLVED: To provide an optical radio transmitter, an optical radio receiver and an optical radio communication system reducing the influence of multiple-reflected light and preventing the deterioration of communication quality.SOLUTION: The optical radio transmitter includes means for generating and composing a signal for canceling a multiple-reflected light component which arrives at the receiver after multiple-reflected by glass etc. in an optical space through the glass in which the glass etc. are existent on a transmission path. This enables the suppression of the influence of the glass etc. on the transmission path. Also, the optical radio transmitter includes means for feeding back information of delay, attenuation, etc. related to the multiple-reflected light component from the reception side to the transmitter.
