ABSTRACT:
This paper reports a channel simulation of an indoor
optical wireless multiple-input-multiple-output (MIMO) system with non-imaging
receivers. The system consists of a 2×2 array of white light-emitting diodes (LEDs) and 2×2 array of
PDs. An overview of the model specifications, channel impulse response and
channel capacity are demonstrated in this paper. The distribution of the first
reflection is analyzed. The effect of SNR and the location of receivers on
non-imaging optical MIMO communications are investigated. In addition, by
moving the receivers, the optimal location of the communication is found.
