- Abstract
- In this paper, we propose a novel modulation that combines the spatial modulation (SM) with the subcarrierintensity-modulation (SIM) for optical wireless communications. The performance of SIM-SM scheme is comparedto a conventional SIM by computer simulation. For the spectral efficiency (SE) of 2bits/s/Hz, the performancegain about 2dB is achieved. As the SE increases to 3bit or 4bits/s/Hz, the Eb/N0 gain becomes about 5dB. It isshown the attenuation for the SIM is more serious than the SIM-SM according to increasing the number of thesubcarriers.
