Abstract
In this paper, a free-space optical link (FSOL) optimization in the visible light communication (VLC) is performed to improve the channel performance for signal strength and analysze the effect of signal failures in a communication system. The problem of uncertainty in the FSOL components for a better signal has prompted this study to check for an improved and enhance signal using bit error rate (BER) analyzer. The light emitting diode (LED) is used as a carrier for transmission of data as the optimization of system properties have concluded for limitations and working conditions. The noise has been added and removed to ascertain the channel behavior which in turn display an acceptable eye diagram for an improved signal. The acceptable eye diagram shows a better signal in the system. The optimization of FSOL will guarantee multi-mobile users of shared signal which will improve the signal errors, loss of power, weak signal, signal failure, loss of data etc. To fully characterize the FSOL, OptiSystem software tool has been used.
