Abstract (in Japanese) (See Japanese page) 
(in English) Spatial OFDM(Orthogonal Frequency Division Multiplexing) which extends optical OFDM to spatial signal has been proposed.However, the high peak of the Spatial OFDM signal degrades BER(Bit Error Ratio) performance because the transmitter has amplitude limitation in LCD camera communication.As a method of reducing that high peak, Parallel Combinatory OFDM has been proposed.Parallel Combinatory OFDM is a method of transmitting information by combination pattern of active subcarrier and inactive subcarrier, in addition to the by phase of the active subcarrier.In this paper, we propose a method combining Spatial OFDM and Parallel Combinatory OFDM, and show that BER performance improves by about 1[dB] by computer simulation compared with the conventional method at large PSNR(Peak Signal to Noise Ratio).
