Spatial modulation with signal space diversity is proposed and experimentally demonstrated using 4-CAP modulation for indoor optical wireless communications. An improved data rate of 7.5 Gb/s is achieved using 2.5 GB/s CAP modulation with rotated CAP constellation and diversity interleaving to enhance BER performance.
