Abstract (in Japanese) (See Japanese page) 
(in English) This paper evaluates transmission performance and spectral efficiency improvement with both an adaptive transmission signal allocation method for inter-lighting interference reduction and an adaptive modulation method in which the optimal modulation scheme is adaptively selected according to transmission channel states by computer simulation in LED visible light wireless communications by spatially parallel signal transmission. The evaluation results show that the methods can increase spectral efficiency by 2.3 times compared with that without these methods.
