Abstract

In this paper, we investigate the indoor near-infrared optical wireless communication (OWC) systems with spatial diversity. Both repetition-coding (RC) and Alamouti-type space-time-block-coding (STBC) schemes are studied to reduce the impact of optical beam blockage in OWC links. Delay-tolerant RC technologies are also discussed to relax the synchronization requirement of transmitters, using the orthogonal filters based scheme or the recurrent neural network (RNN)-based decision scheme.
