Design of Indoor Receiver Using Multiple-Input and Multiple-Output ACO-OFDM Visible Light Communication System
In this study, we design an angle diversity optical receiver using photodiodes with two different fields of view (FOV) for indoor multiple-input and multiple-output visible light communication systems. The system combines the advantages of the receiver with two different FOV (2-FOV) and traditional angle diversity receiver (ADR) to achieve better reception performance. Furthermore, simulation of a typical indoor visible light communication scenario using light-emitting diode lamps as the data transmitters is performed. In our simulation, the minimum signal-to-noise ratio (minSNR) at the output end of an equalizer in the proposed system is higher than those of the 2-FOV receiver and the conventional ADR, which achieves the minSNR of over 45 dB in 97% of indoor locations. The ratio is increased by 96% and 32% compared to those of the 2-FOV receiver and conventional ADR, respectively. Finally, the total bit error rate is calculated for the system using asymmetrically clipped optical orthogonal frequency division multiplexing as the modulation scheme, and the results of the zero-forcing equalizer and minimum mean square error equalizer are given. The results demonstrate that the proposed receiver has the lowest bit error rate for the indoor locations under consideration.
