This paper focuses to analyze the data rate, bit error rate (BER), flickering & bandwidth of visible light communication (VLC) system. The existing modulation scheme ON-OFF Keying (OOK) is modified and produces the trade-off between these parameters. The modified ON-OFF Keying (MOOK) is proposed in which the variation in the transmitted pulses is investigated. Therefore, the square and rectangular pulses are used to transmit zero and one bits respectively. The duty cycle of square pulse is increased to improve the flickering performance. Moreover, it utilized the bandwidth and deteriorates the BER performance. The differential MOOK (DMOOK) modulation scheme is also proposed in which the ON period of square pulse (zero bits) is removed. Therefore, the data rate of DMOOK is increased because the duration of zero bit pulse is decreased. Similarly, the high bandwidth is utilized and BER performance deteriorates. All performance parameters are evaluated on Arduino based hardware VLC system. We conclude that the BER performance deteriorates by improving flickering performance and data rate of the VLC system.
