RECEIVER APPARATUS FOR USE IN OPTICAL SPACE TRANSMISSION SYSTEM

摘要

There are included a plurality of light receiving parts (121,122) that receive respective optical signals (R1,R2) and convert the received optical signals to respective electric signals (r1,r2); a first calculating part (130) that performs a processing to cancel interference components, which occur due to the propagation of the optical signals through the space, for the plurality of electric signals (r1,r2); and a second calculating part (140) that determines, by calculation, whether the distortion, which occurs due to optical beat interference, is equal to or smaller than a predetermined permissible value for the plurality of electric signals (t1',t2') in which the interference components have been cancelled by the first calculating part.
