© 2020 IEEE. A novel spatial modulation channel index detection algorithm using a joint maximum-a-posteriori estimation is proposed for optical wireless communications with 4-CAP modulation and transmitter diversity. Diversity gain, enabling improvement of about 0.4dB in SNR and 1.5-times in data rate, is achieved with reduced computation complexity.
