In order to study the characteristics of multiple input and multiple output (MIMO) channel, first, the basic components of the communication system are analyzed. And then, we present a simplified ray tracing method for optical MIMO system to obtain its channel impulse response and frequency response. This method using ray tracing to calculate the impulse of the channel limits the reflections within three times. Finally, its validity is verified by the numerical simulations, and its simulation results have been discussed. The channel bandwidth i...
