Summary:Optical Wireless Communication (OWC) is superior to radio wireless communication in several technical applications. In order to study the characteristics of Optical Multiple Input Multiple Output (OMIMO) channels, first, this paper presents the simulation of the optical wireless channel to analyze effects of dispersion multipath. We use ray tracing method to calculate the impulse response as well as the frequency response of the channel limit the reflections within seconds. Afterwards, we firstly investigate the OMIMO DCO-OFDM using Space Time Block Code (STBC) of Alamouti in diffuse fading channels to analyze the bit error rate (BER) of the system. The simulation results of the channel, as well as the communication system, are calculated and evaluated specifically.
