Performance Analysis of Indoor Visible Light Communication System with Angle Diversity Transmitter

摘要

In this paper, angle diversity transmitter (ADT) is implemented with indoor visible light communication (VLC) system, namely, VLC-ADT system. The error performance analysis of VLC-ADT system is presented over the line of sight (LOS) VLC channel in a downlink environment. The bit-error-rate (BER) of indoor VLCADT system is analyzed for different receiver locations in the room. The proposed VLC-ADT system reduces the disparity between the minimum and maximum received signal-to-noise ratio (SNR) observed at an optimum semiangle at half illuminance, $emptyset_{1/2}$. The BER performance of indoor VLC-ADT system is also evaluated for the different values of elevation angle considering different locations of the receiver. The simulated results are validated with the analytical results.
